A weight suspended from a spring is seen to bob up and down over a total distance of 20 centimeters twice each second.
Tom [10]

"Twice each second" means "2 per second".  <em>Frequency = 2 Hz.</em>

<em>Period </em>= time for one bounce = <em>1 second</em>

Amplitude = distance between "not stretched" and "greatest stretch".

<em>Amplitude =  10 centimeters</em>

Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a greater frequency than wave Y
____ [38]

Answer:

Wave X has a shorter wavelength.

Explanation:

The relation between the speed of a wave, its wavelength and frequency is given by :

v=f\lambda

It can be seen that the relationship between the frequency and wavelength is inverse.

In this problem, it is mentioned that two sound waves (wave X and wave Y) are moving through a medium at the same speed. The frequency of wave X is greater than wave Y. Then it would mean that wave X have shorter wavelength than wave Y (due to inverse relation).
