What example best illustrates that light behaves like particles?
Which example best illustrates that light behaves like particles? Light bounces off a white cement sidewalk. Zaccharias Janssen was a scientist who studied properties of light and invented one of the first compound microscopes in the late 1500s.
What happens when light from the sun passes through any type of matter?
What happens when light from the Sun passes through any type of matter? The light slows down. The speed of light in glass is slower than the speed of light through space.
Which statement best explains a difference between the interaction of light with clear glass and the interaction of light with silver metal ?’?
Which statement best explains a difference between the interaction of light with clear glass and the interaction of light with silver metal? Most of the light passes through glass but none of the light passes through metal.
Under which color of light will plants be least likely to make food quizlet?
the color of light that is least useful to plants are within the green-yellow range. These colors are filtered out and reflected. This is why plants appear green.
What does light act like when it bounces off a surface?
Reflection is when light bounces off an object. Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection.
Which object absorbs the most visible light?
This means that a black object absorbs the most visible light and converts this light energy to heat.
How are light waves behave?
Light waves across the electromagnetic spectrum behave in similar ways. When a light wave encounters an object, they are either transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered depending on the composition of the object and the wavelength of the light.
What are the examples of light?
There are many example we see in our routine life carrying light energy like lightened candle, flash light, fire, Electric bulb, kerosene lamp, stars and other luminous bodies etc. Each act as a source of light. Even a burning candle is an example for light energy.
How did observations of light being refracted change the way most scientists thought about light?
After the 1600s, how did observations of light being refracted change the way most scientists thought about light? They began to believe that light acted as waves. Which statement correctly compares the speed of light? The speed of light in glass is slower than the speed of light through space.
Which statement best explains why an object appears green in sunlight *?
Which statement best explains why an object appears green in sunlight? The object absorbs most white light and refracts most green light.
Does opaque objects reflect light?
Light cannot shine through opaque materials at all. In fact, opaque materials absorb the light that shines on them. A little of the light is reflected back, though. Each object reflects some light waves of a certain color.
Which type of surface is the best able to reflect light?
The best surfaces for reflecting light are very smooth, such as a glass mirror or polished metal, although almost all surfaces will reflect light to some degree. Reflection of Light When light waves are incident on a smooth, flat surface, they reflect away from the surface at the same angle as they arrive.
Which type of light is least likely used much by plants?
The majority of green light is useful in photosynthesis. The relative quantum efficiency curve (Photo 1) shows how efficiently plants use wavelengths between 300 and 800 nm. Green light is the least efficiently used color of light in the visible spectrum.
What color of light is the best for photosynthesis quizlet?
This occurred because during photosynthesis, chlorophyll a, chlorophyll b, and carotenoids best absorb violet (350 – 450 nm) and red light (620 – 750 nm), but they also absorb white light the best, since it is all wavelengths. These pigments reflect green and yellow light.
Which color of light will drive photosynthesis least effectively in green colored plants?
The green light is considered to be the least efficient wavelength for photosynthesis. During photosynthesis, if the plants are exposed to green wavelength, the rate at which the photosynthesis takes place will be the least. This is due to the presence of a green pigment known as chlorophyll.
How does light behave like a particle?
Red photons, for example, have less energy than blue ones. He theorized that electromagnetic energy comes in packets, or quanta which we now call photons. So light behaves as a wave and as a particle, depending on the circumstances and the effect being observed. This concept is now known as wave-particle duality.
What behavior makes light appear to be a particle?
But Albert Einstein showed us we can also describe light as being made up of individual particles of energy: photons. This is necessary to account for something called the “photoelectric effect”. When you shoot light at a sheet of metal, the metal emits electrons: particles that are electrically charged.
Does light behave like a particle or a wave?
Physicists describe light as both a particle and a wave. In fact, light’s wavelike behavior is responsible for a lot of its cool effects, such as the iridescent colors produced on the surface of bubbles.
What is an example of light absorption?
For example, grass appears green in white light: red, orange, yellow, blue, indigo and violet are absorbed by the grass. green light is reflected by the grass and detected by our eyes.
What are some objects that absorb light?
Coal, black paint, and carbon nanotube arrays — also known as Vantablack — look black because they absorb the energy of the incident light almost completely. Other materials, such as glass or quartz, have no absorbing properties and therefore look transparent.
Which object would reflect the most light?
The best surfaces for reflecting light are very smooth, such as a glass mirror or polished metal, although almost all surfaces will reflect light to some degree. Reflection of Light When light waves are incident on a smooth, flat surface, they reflect away from the surface at the same angle as they arrive.
Which of the following is an example of light behaving like a wave?
When light moves from one medium (like air) to another medium (like water) it will change directions. This is a “wave-like” behavior and is called refraction. In this way light behaves like other waves such as sound waves. You can see an example of refraction of light in water if you put a straw in a glass of water.
Do sound waves behave like light waves?
Light waves are electromagnetic waves while sound waves are mechanical waves. Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.
What is a wave define wave behavior?
All waves behave in certain characteristic ways. They can undergo refraction, reflection, interference and diffraction. These basic properties define the behaviour of a wave – anything that reflects, refracts, diffracts and interferes is labelled a wave.
