Electromagnetic Spectrum and Wave Interactions Quiz

What is the primary characteristic of a wave?

• Always visible to the human eye

• Requires a medium to travel

• Transfers energy without transferring matter

• Transfers matter from one place to another

Which type of wave does not require a medium to travel?

• Electromagnetic waves

• Seismic waves

• Sound waves

• Mechanical waves

What is the electromagnetic spectrum?

• A range of sound frequencies

• A range of all types of mechanical waves

• A range of all types of electromagnetic radiation

• A range of visible light only

What happens during the reflection of light?

• Light passes through a medium

• Light bounces off a surface

• Light changes its speed

• Light is absorbed by the surface

Which law is applied in car mirrors and telescopes?

• Law of absorption

• Law of diffraction

• Law of reflection

• Law of refraction

What is refraction?

• The bending of light as it passes through a medium

• The absorption of light by a material

• The bouncing of light off a surface

• The spreading of light waves

Why does light change direction during refraction?

• Because it is absorbed

• Because it changes speed

• Because it is diffracted

• Because it is reflected

What is diffraction?

• The bending of light as it passes through a medium

• The spreading of light waves through a small opening

• The absorption of light by a material

• The bouncing of light off a surface

What can happen to light when it hits a material?

• It can only pass through

• It can change direction, pass through, or be absorbed

• It can only be reflected

• It can only be absorbed

What is a real-world application of light absorption?

• Using prisms to disperse light

• Using solar panels to harness energy

• Using lenses in glasses

• Using mirrors in telescopes
