Light Quiz

What is visible light?

• Visible light is a form of radio waves that can be detected by a radio receiver.

• Visible light is a type of heat energy that can be felt by the human body.

• Visible light is a form of sound waves that can be heard by the human ear.

• Visible light is a form of electromagnetic radiation that is visible to the human eye.

Which colors are included in the visible light spectrum?

• pink, purple, brown

• red, orange, yellow, green, blue, indigo, and violet

• black, white, gray

• cyan, magenta, turquoise

What is absorption of light?

• The process in which light is absorbed by a material and its energy is converted into other forms of energy.

• The process in which light is reflected by a material and its energy is converted into other forms of energy.

• The process in which light is transmitted through a material and its energy is converted into other forms of energy.

• The process in which light is emitted by a material and its energy is converted into other forms of energy.

When light is absorbed by an object, what happens to the energy of the light?

• The energy of the light is destroyed.

• The energy of the light is reflected back.

• The energy of the light is converted into sound waves.

• The energy of the light is converted into heat or other forms of energy.

What is reflection of light?

• The emission of light by an object when it is struck by another light source.

• The bouncing back of light when it strikes the surface of an object and does not pass through it.

• The absorption of light by an object when it strikes its surface.

• The bending of light as it passes through a medium.

What happens when light reflects off a smooth surface?

• The angle of incidence has no relation to the angle of reflection.

• The angle of incidence is equal to the angle of reflection.

• The angle of incidence is less than the angle of reflection.

• The angle of incidence is greater than the angle of reflection.

What is rarefaction of light?

• Reflection of light waves off a surface

• Increase in density or intensity of light waves

• Decrease in density or intensity of light waves

• Absorption of light waves by a medium

In which type of medium does rarefaction of light occur?

• High refractive index medium

• Dark medium

• Opaque medium

• Transparent medium
