Basic Waves

Waves that require a medium are called 

• mechanical waves
• transverse waves
• light waves
• gamma rays

What kind of wave is pictured below?

• compressional wave
• transverse wave
• sound wave
• mechanical wave

What do we call the part of a longitudinal wave that is spread a part?

• compression
• rarefaction
• crest
• trough

What is frequency?

• any disturbance that transmits energy through a medium
• the distance from any point on a wave to an identical point on the next wave
• the number of waves produced in a given amount of time
• when the particles in a longitudinal wave are spread apart

What is a medium?

• something between a small and a large?
• the substance through which a wave can travel
• a pattern of vibration that simulates when a wave is standing still
• the distance from any point on a wave to an identical point on the next wave

What wave has rarefaction and compression?

• longitudinal 
• surface
• heat
• transversal

Based on the picture, choose the best description of how wavelength and frequency are related

• As wavelength increases, frequency increases
• As frequency increases, wavelength remains the same
• As frequency increases, wavelength decreases
• frequency and wavelength mean the same thing
