Question

A certain radio wave has a frequency of 2.0 10^6 Hz. What is its wavelength? Don't understand how to solve!!! Help!!!!

Answer 1

2.0*10^6

Answer 2

Use the universal wave equation\[v=f \lambda\]Radio waves travel at the speed of light, so you know the value of v. And frequency is given. So solve for wavelength lambda

Answer 3

@ospreytriple what do I multiply 2.0*10^6 by?

Answer 4

You have\[v=3.0\times 10^8 \frac{ \text{m} }{ \text{s} } \text{ and }f=2\times10^6 \text{ Hz}\]Rearrange and solve for lambda.

Answer 5

ok thank you!!

Answer 6

You're welcome.
