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.

If the angle of incidence is 30 degrees, what is the angle of reflection?

• 20 degrees

• 30 degrees

• 45 degrees

• 60 degrees

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.

What type of surface is best for reflection?

• A rough, matte surface, like sandpaper.

• 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.
