Sound Waves
100

This type of wave vibrates matter in compressions and rarefactions.  

What is a longitudinal wave?

100

when a wave strikes the medium and bounces off at the exact angle is called?

What is reflection?

100

A vertical distance between a peak and the resting position in a transverse wave is called?

Amplitude?

100

The distance from peak to peak

What is wavelength?

100

What type of wave is a sound wave?

longitudinal

200

This type of wave vibrates matter in perpendicular to the direction of the wave.

What is a transverse wave?

200

how a wave bends as it moves from one medium into another

What is refraction?

200

What type of wave has crests and troughs?

Transverse waves

200

What part of a wave measures/determines loudness?


amplitude

200

If you were in outerspace, would anybody be able to hear you scream?

No. Require medium to travel through

300

This type of wave does not need matter to transfer energy.

What is an electromagnetic wave?

300

angle of incidence is 40o, what is the angle of reflection

40o

300

The matter that mechanical waves travel through is known as ____________.

What is a medium?

300

What happens when the pitch gets lower?

Frequency becomes lower; energy becomes lower

300

Sound waves travel the fastest in what medium? The slowest in what medium?

fastest- solids

slowest- gases

400

Which EM wave has the longest wavelength?

Radio waves

400

When light passes through a medium and scatters

Diffusion

400

The number of wave oscillations or cycles is called?



Frequency





400

How can you tell if a wave has a high amount of energy?

Look at the frequency.

Closer=more energy

400

Explain why sound waves travel the fastest in solids.

solids: particles very tightly packed therefore sound waves can vibrate off of the particles very quickly. 

500

Mechanical waves include what types of waves

longitudinal and transverse

500

When light hits a medium but does not pass through and does not reflect

absorbs

500

What type of wave can travel through a vacuum?

EM Wave

(Radio, Light, UV, Infrared, Microwave)

500

The number of wavelengths that pass a given point per second.

What is frequency?

500
Explain how you would perceive the sound of a firetruck siren as it speeds towards you and speeds away from you.

towards you: short wavelength, high frequency, high pitch

away from you: long wavelength, low frequency, low pitch
