A certain radio wave has a frequency of 2.0*10^6 Hz. What is its wavelength?
c=3*10^8 m/s
wavelength = 3*10^8
_______
2*10^6
= 150 m
is this done correctly?
Yes
How to do frequency radio wavelenghts
No, your calculation is incorrect. The formula to calculate wavelength is:
wavelength = speed of light / frequency
Given that the speed of light is 3 * 10^8 m/s and the frequency is 2.0 * 10^6 Hz, the calculation should be:
wavelength = (3 * 10^8 m/s) / (2.0 * 10^6 Hz)
Simplifying this, we get:
wavelength = 150 m
So the correct answer is 150 meters.
Yes, your calculation is correct. To find the wavelength of a wave, you can use the formula: wavelength = speed of light / frequency. Given that the speed of light (c) is 3*10^8 m/s and the frequency is 2.0*10^6 Hz, you can substitute these values into the formula.
So, wavelength = 3*10^8 m/s / 2.0*10^6 Hz = 150 m. The wavelength of the radio wave is 150 meters. Great job!
