A Discussion On Wave Properties
If you slosh the water back and forth in a bathtub at the correct frequency, the water rises first at one end and then at the other. Suppose you can make a standing wave in a 183 cm long tub with a frequency of 0.2222 Hz.

Radio waves: wavelengths of the radio signals
Wavelength = Speed / Frequency
Speed= 300,000,000 m/s
a) Frequency= 97.5 MHz= 97,500,000 Hz
Therefore, wavelength= Speed/frequency = 3.0769 m =300,000,000/97,500,000
Answer: Wavelength = 3.0769 m

Find the frequency of an EM wave.
We have for the velocity of a wave,
C = frequency * wavelength
for an EM wave, C = 3*10^8 m/s
Here wavelength = 6m
therefore frequency f = C/wavelength = 3*10^8/6 = 5*10^7 Hz
The velocity of a wave: C = frequency * wavelength.

Evaluating Standing Waves
frequency will be 354HZ( to be calculated as in Q5)
(c) Frequency will be halved:
L + 2*0.6r = 1/2 wavelength of standing wave
91.4 + 1.38 = 1/2 wavelength
92.78 = 1/2 wavelength
wavelength = 185.6 cm
frequency = 34300/185.6
= 184.8 Hz

Calculate the wavelength of a string moved up and down given velocity and frequency.
Velocity = frequency x wavelength
40 = 125 x wavelength
wavelength = 40/125 = 0.32m The wavelengths of a string moving up and down for a given velocity and frequency are determined.

Types of waves: Speed, frequency & wavelength
Find the wavelength of the waves in the shallower water. speed = wavelength*frequency
frequency = 2/1.5 (s^-1)
so, in shallow water, wavelength = 1.6/(2/1.5) = 1.2 m The solution briefly explains the problem and solves it.

Relationships between wavelength, frequency, and energy of light.
v is the frequency of light; and (2) the relationship between the frequency of light and the wavelength of light:
v=c/L, where v = frequency, c=the speed of light(3.00 x 10E8m/s), and L = wavelength.
