What is the law of reflection?

• The angle of incidence equals the angle of reflection.

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

• The angle of reflection is always zero degrees.

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

How does light behave when it hits a smooth surface?

• Light passes through a smooth surface without any change.

• Light absorbs into a smooth surface completely.

• Light scatters in all directions when it hits a smooth surface.

• Light reflects off a smooth surface at equal angles of incidence and reflection.

What is the difference between regular and diffuse reflection?

• Diffuse reflection creates clear images, while regular reflection scatters light.

• Regular reflection occurs only on smooth surfaces, while diffuse reflection happens on rough surfaces.

• Regular reflection produces clear images, while diffuse reflection scatters light and does not produce clear images.

• Regular reflection is only seen in mirrors, whereas diffuse reflection is seen in all materials.

Define refraction of light.

• Refraction of light is the bending of light as it passes from one medium to another.

• Refraction of light is the absorption of light by a medium.

• Refraction of light is the scattering of light in all directions.

• Refraction of light is the reflection of light off a surface.

What happens to light when it passes from air into water?

• Light speeds up and changes color when entering water.

• Light passes straight through without any change.

• Light bends and slows down when it passes from air into water.

• Light disappears completely when it hits the water surface.

What is the refractive index?

• The refractive index is the color of light in different materials.

• The refractive index is the angle at which light enters a medium.

• The refractive index is the ratio of the speed of light in vacuum to the speed of light in a medium.

• The refractive index is the measure of light intensity in a medium.

How do lenses bend light?

• Lenses bend light by absorbing it completely.

• Lenses bend light by changing its color.

• Lenses bend light by reflecting it off their surface.

• Lenses bend light by refraction, altering the path of light rays based on their shape.

What are the two main types of lenses?

• Convex lenses and concave lenses

• Polarizing lenses and tinted lenses

• Flat lenses and spherical lenses

• Biconvex lenses and biconcave lenses

What is the function of a convex lens?

• To absorb light and prevent reflection.

• To diverge light rays and create shadows.

• To filter light and change its color.

• The function of a convex lens is to converge light rays and magnify images.

What type of mirror is used in a rearview mirror?

• Concave mirror

• Convex mirror

• Parabolic mirror

• Flat mirror
