Question

What is the wavelength of an electromagnetic wave that travels at 3 10 m/s and has a frequency of 60 mhz? (1 mhz = 1,000,000 hz)?

Answer 1

v = 310 m/s
f = 60 MHz = 60 × 10^6 Hz
v = xf
x = v/f
x = 310/(60 × 10^6) m
x = 5.166667 × 10^(−6) m

Answer 2

`\lambda = 5 m`

Step-by-step explanation:

As we know the electromagnetic waves can travel through the vacuum with speed

`c = 3 * 10^8 m/s`

now we also know that the frequency of the electromagnetic waves is given as

`f = 60 MHz`

so the wavelength of the electromagnetic waves is given as

`\lambda = (c)/(f)`

so it is given as

`\lambda = (3 * 10^8)/(60 * 10^6 Hz)`

`\lambda = 5 m`
