Reflection and Refraction of light

What is the angle of incidence?

• The angle between the incoming light ray and the normal line at the surface.

• The angle between two incoming light rays.

• The angle between the outgoing light ray and the surface.

• The angle formed by the surface and the light ray.

What happens to light when it is absorbed by an object?

• It bounces back and reflects off the surface.

• It is taken in by the object.

• It changes color and becomes visible.

• It travels through the object without any change.

What is an example of refraction?

• A straw appearing bent in a glass of water

• A rainbow forming after rain

• A shadow cast by an object

• A mirror reflecting an image

What is dispersion of light?

• Dispersion is the bending of light as it passes through a lens.

• Dispersion is the separation of light into its different colors, as seen in a rainbow.

• Dispersion is the reflection of light off a surface.

• Dispersion is the absorption of light by a material.

What is refraction?

• The reflection of light off a surface.

• The bending of light as it passes from one medium to another.

• The scattering of light in different directions.

• The absorption of light by a material.

What does the law of reflection state?

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

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

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

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

What is an example of light being reflected?

• Light passing through a window

• Light bouncing off a mirror

• Light being absorbed by a black surface

• Light scattering in the atmosphere

What is total internal reflection?

• Total internal reflection occurs when light hits a boundary at a steep angle and reflects back into the medium.

• Total internal reflection is the process of light passing through a medium without any reflection.

• Total internal reflection happens when light is absorbed by the medium it enters.

• Total internal reflection occurs when light bends at a shallow angle and exits the medium.

What is reflection?

• Reflection is when light bounces off a surface, like a mirror.

• Reflection is the process of absorbing light by a surface.

• Reflection is the bending of light as it passes through a medium.

• Reflection is the scattering of light in different directions.

What is the angle of reflection?

• The angle between the incident light ray and the normal line at the surface.

• The angle between the reflected light ray and the normal line at the surface.

• The angle between the surface and the light ray.

• The angle between two reflected light rays.
