Unit 8 Test: Waves, Light, Sound

Front

What is Reflection in terms of light?

Back

Reflection is the bouncing back of light when it hits a surface. It allows us to see objects as they reflect light into our eyes.

Front

What does a wave transfer as it travels through a medium?

Back

A wave transfers energy as it travels through a medium, not matter.

Front

What is Refraction?

Back

Refraction is the bending of light as it passes from one medium to another, causing objects to appear distorted or displaced.

Front

Which medium allows sound waves to travel the fastest?

Back

Sound waves travel fastest through solids, such as wood, because the particles are closer together.

Front

What is the Electromagnetic (EM) Spectrum?

Back

The EM spectrum is the range of all types of electromagnetic radiation, ordered by frequency and wavelength.

Front

List the EM spectrum in order from lowest frequency to highest frequency.

Back

Radio Waves, Microwaves, Infrared, Visible Light, Ultraviolet, X-Rays, Gamma Rays.

Front

What is Diffraction?

Back

Diffraction is the bending of waves around obstacles and openings, which can cause patterns of light and sound.

Front

What is Interference in wave behavior?

Back

Interference occurs when two or more waves overlap and combine to form a new wave pattern.

Front

What is the difference between a transverse wave and a longitudinal wave?

Back

In a transverse wave, the particle movement is perpendicular to the wave direction, while in a longitudinal wave, the particle movement is parallel to the wave direction.

Front

What is the speed of sound in air compared to water?

Back

Sound travels faster in water than in air due to the closer proximity of water molecules.
