Review Wave Quiz

List three types of waves:

Answer explanation

Transvers, Longitudinal, ripples, bow/shock

List and draw the characteristics of transverse and longitudinal waves.

Answer explanation

What do waves travel through?

Answer explanation

A medium

Define mechanical waves.

• A disturbance that transfers energy

• a wave a mechanic uses

• wave technology

• bow wave

List 2 types of mechanical waves and give examples of each.

Answer explanation

Transverse-water, light

Longitudinal-sound

What is constructive and deconstructive interference?

Answer explanation

Constructive intereference increases amplitude, and deconstructive interference canels.

Write the Wave equation (as best as possible):

Answer explanation

Radio station WKLB in Boston broadcasts a frequency of 99.5x10^6 MHz. What is the wavelength of the radio waves emitted by WKLB? (Speed=3.00x 10^8 m/s) SHOW YOUR WORK (as best as possible)

Answer explanation

Speed=wavelength times frequency. Wavelength=3.00x10^8 m/s times 99.5x10^6 MHz.

Wavelength is 3.02 m

One end of the rope is vibrated to produce a wave with a wavelength of .25 m.  The Frequency of the wave is 3.0 Hz.  What is the speed of the wave? SHOW YOUR WORK (as best as possible):

Answer explanation

Speed=wavelength times frequency.

.25m times 3.0Hz

Speed =.75 m/s

A wave has frequency of 35 Hz and a wavelength of 12 m. What is the speed of the wave? SHOW YOUR WORK (as best as possible):

Answer explanation

Speed=wavelength times frequency.

12m times 35Hz.

Speed=420m/s
