A) Canadian FM radio station (CLAW) broadcasts lobster information at 95.9 MHz. find the wavelength of this station. (B) What would be the frequency of a station for which the carrier wave was 400 m long?
didn't I just answer this?
To find the wavelength, you can use the formula:
wavelength = speed of light / frequency
The speed of light is a constant value, approximately 299,792,458 meters per second.
A) For the Canadian FM radio station (CLAW) broadcasting at 95.9 MHz:
First, convert the frequency from MHz to Hz:
95.9 MHz = 95.9 million Hz = 95,900,000 Hz
Now, substitute the values into the formula:
wavelength = 299,792,458 / 95,900,000
Using a calculator:
wavelength ≈ 3.125 meters
Therefore, the wavelength of the Canadian FM radio station CLAW is approximately 3.125 meters.
B) For a carrier wave length of 400 meters:
Use the same formula:
wavelength = speed of light / frequency
Substitute the values into the formula:
400 = 299,792,458 / frequency
Now, rearrange the equation to solve for the frequency:
frequency = 299,792,458 / 400
Using a calculator:
frequency ≈ 749,481.15 Hz
Therefore, the frequency of a station for which the carrier wave is 400 meters long would be approximately 749,481.15 Hz.
