FM means frequency modulation, and AM means amplitude modulation.
AM = amplitude modulated. FM = frequency modulated.
To find the frequency of a radio wave, you can use the formula ( f = \frac{c}{\lambda} ), where ( f ) is the frequency, ( c ) is the speed of light (approximately ( 3.00 \times 10^8 ) m/s), and ( \lambda ) is the wavelength. Given a wavelength of 2.5 m, the frequency is calculated as ( f = \frac{3.00 \times 10^8 \text{ m/s}}{2.5 \text{ m}} = 1.2 \times 10^8 \text{ Hz} ) or 120 MHz.
AM - amplitude modulation MHz - Mega Hertz. The M means one million (1000000).
The wavelength of a radio wave can be calculated using the formula ( \lambda = \frac{c}{f} ), where ( \lambda ) is the wavelength, ( c ) is the speed of light (approximately ( 3 \times 10^8 ) meters per second), and ( f ) is the frequency in hertz. For a radio wave of frequency ( f ) Hz, the wavelength would be ( \lambda = \frac{3 \times 10^8 \text{ m/s}}{f} ). Thus, to find the specific wavelength, simply divide the speed of light by the given frequency.
The formula for calculating frequency is f = v/λ, where f is the frequency, v is the speed of the wave, and λ is the wavelength. Plugging in the values given, we get f = 840 m/s / 0.023 m = 36521.74 Hz. Therefore, the frequency of the wave is approximately 36521.74 Hz.

Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.
EM waves travel at the speed of light in a vacuum. c=f*lambda where c is the speed of light, f is the frequency of the way and lambda is the wavelength. Lambda= c/f = (3x108 m/s)/3x1010 s-1) = 1x10-2 m or 1 cm
The frequency is 1000000000 Hz.
The general formula for a moving wave is: v = f λ where v is speed (in m/s), f is frequency (in Hz) and λ is wavelength (in m) For EM radiation, the speed is a constant (speed of light = c ≈ 300,000,000 m/s), so you can derive frequency as: f = c/ λ

The frequency of light can be calculated using the equation ( f = \frac{c}{\lambda} ), where ( f ) is the frequency, ( c ) is the speed of light (approximately ( 3 \times 10^8 ) meters per second), and ( \lambda ) is the wavelength. For ultraviolet light with a wavelength of 10 meters, the frequency would be ( f = \frac{3 \times 10^8 , \text{m/s}}{10 , \text{m}} = 3 \times 10^7 , \text{Hz} ) or 30 MHz. However, it's worth noting that a wavelength of 10 meters falls within the radio wave range, not ultraviolet light.
