Reflection Quiz

What is reflection?

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

• Reflection is the change in direction of a wavefront at an interface between two different media.

• Reflection is the absorption of light by a surface

• Reflection is the process of light passing through a transparent object

Give an example of reflection in everyday life.

• Looking at yourself in the mirror

• Reading a book

• Cooking dinner

• Watching TV

What type of surface reflects light better: smooth or rough?

• Rougher

• Bumpy

• Textured

• Smooth

Explain the difference between regular reflection and diffuse reflection.

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

• Regular reflection reflects light rays at the same angle they hit the surface, while diffuse reflection scatters light rays in different directions.

• Regular reflection absorbs light rays, while diffuse reflection reflects them.

• Regular reflection scatters light rays in different directions, while diffuse reflection reflects light rays at the same angle they hit the surface.

How does a mirror reflect light?

• By creating its own light source

• By reflecting light according to the law of reflection.

• By refracting light at an angle

• By absorbing light and emitting it back

Why do we see our reflection in a mirror?

• Our reflection is a result of the mirror absorbing light

• Light bounces off the mirror's surface and reflects back to our eyes.

• Mirrors emit light that creates our reflection

• Our reflection is projected onto the mirror's surface

What is the law of reflection?

• Angle of incidence = Angle of reflection

• Light bends towards the normal

• Angle of reflection = Angle of refraction

• Angle of incidence = 90 degrees

What is the angle of incidence?

• The angle of incidence is the angle formed between the normal and the reflected ray

• The angle of incidence is the angle formed between the incident ray and the reflected ray

• The angle of incidence is the angle formed between the reflected ray and the surface

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

What is the angle of reflection?

• Opposite to the angle of incidence

• 90 degrees

• Equal to the angle of incidence

• Double the angle of incidence

How can you change the direction of a reflected light ray?

• Change the wavelength of the light

• Change the angle of incidence

• Change the color of the light

• Change the speed of the light
