Understanding Light Reflection

What is light reflection?

• Light reflection is the scattering of light in all directions.

• Light reflection is the conversion of light into heat energy.

• Light reflection is the bouncing of light off a surface.

• Light reflection is the absorption of light by a surface.

Name the law that governs reflection of light.

• Theory of Dispersion

• Principle of Diffraction

• Law of Reflection

• Law of Refraction

What is the angle of incidence?

• The angle of incidence is the angle formed by the surface and the ground.

• The angle of incidence is the angle between two incoming rays.

• The angle of incidence is the angle between the outgoing ray and the surface.

• The angle of incidence is the angle between the incoming ray and the normal to the surface.

What is the angle of reflection?

• The angle of reflection is always 90 degrees.

• The angle of reflection varies with the surface texture.

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

• The angle of reflection is half of the angle of incidence.

How does a mirror reflect light?

• A mirror refracts light by bending it through its surface.

• A mirror reflects light by bouncing it off its smooth surface, following the law of reflection.

• A mirror emits light from its surface to create images.

• A mirror absorbs light and converts it into heat.

What happens to light when it hits a rough surface?

• Light travels in a straight line.

• Light is absorbed completely.

• Light scatters in many directions.

• Light reflects back in a single direction.

Can light reflect off water?

• Light only absorbs in water, no reflection occurs.

• No, light cannot reflect off water.

• Yes, light can reflect off water.

• Water does not interact with light at all.

What is a real-life example of light reflection?

• Seeing a rainbow in the sky.

• Seeing your reflection in a mirror.

• Observing a shadow on the ground.

• Watching a movie in a theater.

What type of image is formed by a plane mirror?

• Inverted and of different size than the object

• Virtual but larger than the object

• Real and inverted

• Virtual, upright, and of the same size as the object.

How does the color of an object affect light reflection?

• The color of an object only affects its temperature, not light reflection.

• All colors reflect light equally regardless of their wavelengths.

• The color of an object affects light reflection by determining which wavelengths of light are reflected and which are absorbed.

• The color of an object has no effect on light reflection.
