Light & Sound Study Set

How does Light Travel?

• A usage of salt and water

• Bouncing of sound waves

• In straight lines: a term called rays

• By walking

Answer explanation

Light, travels in straight lines called rays. They can also travel in waves. Specific waves can be Transverse Waves as they do have certain parts.

What are the parts to a Transverse Wave?

• Crest, Wavelength, & trough

• Crest, Amplitude, & Trough

• Head, Knees, & toes

• Wavelength, Crest, & length

Answer explanation

The wave parts are: Crests, Wavelength, & Trough

How would you explain the movement of Sound?

What is Reflection?

• The movement of water

• The exact formula of pi.

• The amplitude of a sound wave.

• The bouncing of Light off a surface. Objects are mostly smooth or shiny.

What is Refraction?

• The bouncing of objects

• The bouncing of sound

• When an object looks like it's in two places at once: Light Bending

• Light Bouncing

Answer explanation

When an object looks like it's in two places at once: Light Bending

True or False: Does a Prism show all of the visible spectrum colors due to the white light refracting/bending?

• True

• False

Answer explanation

As light passes through this prism we can see that  white light is a mixture of all the colors. This is due to refraction.
