Light Quiz

What is the law of reflection?

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

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

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

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

Explain the difference between regular and diffuse reflection.

• Regular reflection only occurs with certain types of materials, while diffuse reflection occurs with all materials.

• Regular reflection and diffuse reflection are the same thing.

• Regular reflection occurs when light rays are reflected in a single direction, while diffuse reflection occurs when light rays are reflected in many different directions.

• Regular reflection occurs when light rays are reflected in many different directions, while diffuse reflection occurs when light rays are reflected in a single direction.

What is the difference between refraction and reflection?

• Refraction is the absorption of light by a surface, while reflection is the passing of light through a medium.

• Refraction is the bending of light as it passes from one medium to another, while reflection is the bouncing back of light when it hits a surface.

• Refraction is the bending of sound waves, while reflection is the bending of light waves.

• Refraction is the change in color of light, while reflection is the change in direction of light.

Explain the concept of total internal reflection.

• Partial internal reflection

• Total internal reflection

• Total external reflection

• Complete external reflection

How do different materials affect the speed of light?

• Different materials have no effect on the speed of light

• Different materials can make light disappear

• Different materials can affect the speed of light by either slowing it down or speeding it up.

• Different materials can change the color of light

What are the optical properties of a concave lens?

• Absorbing

• Converging

• Reflecting

• Diverging

How does the color of an object relate to the light it reflects?

• The color of an object is determined by the wavelengths of light it reflects.

• The color of an object is determined by the size of the light it reflects.

• The color of an object is determined by the temperature of the light it reflects.

• The color of an object is determined by the speed of the light it reflects.

Explain the concept of complementary colors.

• Complementary colors are pairs of colors that, when combined, cancel each other out.

• Complementary colors are colors that create a harmonious blend when combined.

• Complementary colors are colors that are identical to each other.

• Complementary colors are colors that are completely opposite to each other on the color wheel.
