Light Quiz

What is the law of reflection?

• The angle of incidence is greater than 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.

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

Explain the difference between regular and irregular reflection.

• Regular reflection is caused by diffraction, while irregular reflection is caused by refraction.

• Regular reflection occurs when light rays are reflected uniformly in a single direction, while irregular reflection occurs when light rays are reflected in multiple directions.

• Regular reflection only occurs with opaque surfaces, while irregular reflection only occurs with transparent surfaces.

• Regular reflection occurs when light rays are reflected in multiple directions, while irregular reflection occurs when light rays are reflected uniformly in a single direction.

What is dispersion of light?

• Separation of light into its different colors

• Combining of light into a single color

• Absorption of light by an object

• Reflection of light off a surface

How does a prism separate white light into its component colors?

• Absorption

• Reflection

• Diffraction

• Refraction

Name two optical devices used to correct vision.

• Binoculars and telescopes

• Glasses and contact lenses

• Microscopes and magnifying glasses

• Sunglasses and safety goggles

Explain how a microscope uses lenses to magnify an image.

• A microscope uses prisms to magnify an image.

• A microscope uses concave lenses to magnify an image.

• A microscope uses a combination of convex lenses to bend light and focus it on the specimen, which magnifies the image.

• A microscope uses mirrors to magnify an image.

What is the visible spectrum of light?

• Range of wavelengths visible to the human eye

• Infrared light spectrum

• Ultraviolet light spectrum

• Sounds produced by light

How does the human eye perceive different colors?

• By the stimulation of different types of cone cells in the retina

• Through the absorption of light by the cornea

• By the activation of different types of rod cells in the retina

• By the reflection of different wavelengths of light by the lens

How are different colors produced by mixing light?

• Subtractive color mixing

• Additive color mixing

• Using black and white to create different shades

• Mixing different types of light bulbs

What is the relationship between the frequency of light and its color?

• The frequency of light has no relation to its color.

• The frequency of light determines its color.

• The color of light determines its frequency.

• The frequency of light is determined by its intensity.
