Calculate the wavelength of a wave of frequency 40 MHz propagating in a medium Speed of light-(3*10to the power 5. )
L = V/F = 3*10^5/40*10^6 = 0.0075 m.
To calculate the wavelength of a wave, you can use the formula:
wavelength = speed of light / frequency
Given that the speed of light is 3 * 10^5 m/s and the frequency is 40 MHz, first, convert the frequency to Hz:
40 MHz = 40 * 10^6 Hz
Now, substitute the values into the formula:
wavelength = (3 * 10^5 m/s) / (40 * 10^6 Hz)
Simplifying:
wavelength = 7.5 meters
Therefore, the wavelength of the wave is 7.5 meters.
To calculate the wavelength of a wave, you can use the formula:
Wavelength = Speed of Light / Frequency
In this case, the given frequency is 40 MHz and the speed of light in the medium is 3 * 10^5 m/s.
Let's plug in these values into the formula:
Wavelength = (3 * 10^5 m/s) / (40 * 10^6 Hz)
Now, let's simplify the equation:
Wavelength = (3 * 10^5 m/s) / (4 * 10^7 Hz)
To simplify further, we can cancel out a factor of 10^5:
Wavelength = 3 / 4 * 10^2 m
Therefore, the wavelength of the wave is 0.0075 meters or 7.5 millimeters.
