Self-test 1A.1B

Postby AnvitaaAnandkumar_1B » Wed Oct 09, 2019 11:10 am

What is the wavelength of the signal from a radio station transmitting at
98.4 MHz?

I believe since we use the equation c = w*f, then 3e8= 98.6e6x. to solve for x (wavelength) then divide by the frequency. I got 3.05 meters.

Are c and w*f constant values in the equation you used?

C is a constant value which is the speed of light. Lavelle introduced it in lectures as 3.00x10^8 m/s in a vacuum. I'm assuming w and f stand for wavelength and frequency which are not constants since they will be different depending on the problem.

w= wavelength, f= frequency, c= speed of light (3e8)
