100 MHz, and the 'hint' doesn't help you find this answer at all.

It only tells you how to write it once you find it.

Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.

The equation for frequency is f=v/λ where f= Frequency,

v= Phase Velocity or in basic physics just velocity,

λ= Wavelength

But there is a special case where if electromagnetic waves are in a vacuum then v=c where C= The speed of Light

so you have 3x10-4 = c/λ or λ=c/3x10-4

so if you sub in the speed of light for c=299,792,458m/s then you get

λ= 999308193333.333333333m

or in appropriate significant figure notation

λ= 9x1011m

Wavelength = (speed) divided by (frequency)

Speed of light, radio, infrared, x-rays, etc. = 300,000,000 meters/sec

Wavelength = (300,000,000 / 3,000,000) = 100 meters.

You can't see that wavelength, and it's not usually described as "light".

It's in the region of the electromagnetic spectrum known as "radio".

Because the speed is in m/s, you need to convert the frequency from megaherz to hz, which is /s.

Convert MHz to Hz

60 MHz x 1 000 000 Hz/MHz = 60 000 000Hz = 6 x 107Hz

Known:

f = 6 x 107Hz

c = 3 x 108 m/s = speed of light in a vacuum

Unknown: wavelength, λ

Equation:

c = ƒ•λ, where f if frequency in Hz, λ is the wavelength in meters, and c is the speed of light in a vacuum in m/s.

Solution:

λ = c/ƒ = (3 x 108 m/s) / (6 x 107Hz) = 5 m

==========================

Summary, for shorter attention-spans:

Wavelength = (speed)/(frequency) = (3 x 108)/(60 x 106)= 5 meters

Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.

Since the speed of the wave is equal to the wavelength times the frequency, all you need to do is divide the speed by the wavelength in this case.

An electromagnetic wave has a velocity "c", the universal wave equation velocity = wavelength * frequencythe wavelength then equal c / frequencythen the wavelength of that wave is : Lambda= c / Nu= 299792458 / 3*1000000 = 99.930819333333333333333333333333 meters ~ 100 meters(Lambda is the wavelength, Nu is the frequency).====================================To summarize:Wavelength = (speed) / (frequency) = (3 x 108) / (3 x 106) = 102 = 100 meters, in vacuum

If u meant radio wave, then velocity of all electromagnetic wave is 3*108 m/s. Hence velocity of radio wave will be the same ,as it as an em wave, irrespective of its wavelength.

apex - 3.6 . to find the wave speed you multiply the frequency and the wave length .
