Light travels in straight lines as electromagnetic waves. True or False?
True
What is the angle at which light bounces off a surface?
angle of reflection
Light passes through all materials in the same way. True or False?
False
What happens to light when it gets absorbed?
It turns into heat on the surface it got absorbed by.
What happens when light hits a rough surface?
It scatters light in all directions.
The angle at which the light reflects is _________ to the angle at which it hits the surface.
equal
What happens during light transmission?
Light passes through a material without being absorbed or reflected.
Why do you feel hot when wearing dark colored materials under the sun?
Darker colored materials tend to absorb more light than lighter colored materials.
What type of scattering causes the sky to be blue?
Rayleigh scattering
What type of reflective surface gives a clear reflection?
Smooth surfaces
What kind of material creates a shadow?
Opaque
What color would an object appear when it absorbs all colors of light?
black
What is Tyndall Effect?
scattering of light in colloidal solutions, making the beam visible.
What type of reflection occurs on a smooth surface?
specular reflection
What kind of material is air?
transparent
Why is the sky blue?
Sky is blue because of light scattering. Light with shorter wavelengths scatters more. Blue has a short wavelength, so it scatters a lot in the atmosphere.
What kind of reflection is produced when light hits a rough surface?
Diffuse reflection
Which of the following materials does not belong to the group?
eyeglasses, shower curtain, window, water
shower curtain
