Recall Activity: Law of Reflection

What happens to light when it strikes a mirror?

• It passes through the mirror without any change.

• It absorbs into the mirror's surface.

• It reflects off the surface according to the Law of Reflection.

• It scatters in multiple directions.

Define angle of incidence.

• The angle formed between the incident ray and the normal at the point of incidence.

• The angle formed between two reflected rays.

• The angle between the surface and the incident ray.

• The angle formed between the incident ray and the surface.

What is the Law of Reflection?

• The Law of Reflection states that light travels in a straight line until it hits an object.

• The Law of Reflection states that the angle of incidence is equal to the angle of reflection when light reflects off a surface.

• The Law of Reflection states that light can bend when it passes through different mediums.

• The Law of Reflection states that light is absorbed by dark surfaces and reflected by light surfaces.

How does the angle of incidence affect the angle of reflection?

• The angle of incidence has no effect on the angle of reflection.

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

• The angle of incidence directly determines the angle of reflection; they are always equal.

• The angle of incidence only affects the speed of the reflected wave.

What is reflection in terms of light?

• Reflection is the bending of light as it passes through different mediums.

• Reflection is the bouncing of light off the surface that it strikes on.

• Reflection is the absorption of light by a surface.

• Reflection is the scattering of light in different directions.

What is an example of reflection in everyday life?

• Seeing your image in a mirror is an example of reflection.

• The sound of an echo bouncing off a wall.

• The way light bends when passing through a lens.

• The process of thinking deeply about a situation.

• A smooth, shiny surface, like a mirror.

• A textured surface, like a wall.

• A transparent surface, like glass.

What is the difference between reflection and refraction?

• Reflection is the bending of light as it passes through different mediums, while refraction is the bouncing of light off a surface.

• Reflection is the bouncing of light off a surface, while refraction is the bending of light as it passes through different mediums.

• Reflection and refraction are the same phenomenon occurring under different conditions.

• Reflection occurs only in water, while refraction occurs in air.

What is the relationship between the angle of incidence and the angle of reflection?

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

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

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

• The angle of incidence and angle of reflection are unrelated.
