Describe the relationship between wavelength and frequency for electromagnetic radiation. What is the principle difference between a radio wave, light, and x-rays?

Expert Solution

For electromagnetic waves the frequency of the wave can be formulate as

frequency=velocity of light/wave length

Let consider

c=velocity of light or velocity of electromagnetic wave

f=frequency of the electromagnetic wave

∆=wave length of electromagnetic wave

Therfore from the formula I have mention above

f=c/∆

Therfore form above expression you can see that frequency inversely proportional to the wavelength of electromagnetic wave

Hence as the frequency is increases wavelength decrease or vice versa

The principle difference between the radio wave ,light wave ,and X Ray is their wavelength and frequency

The wavelength of radio wave is greater than the light wave and X Ray and hence frequency of radio wave is less than the light wave and X Ray .

The order of the wavelength are as follow:

Wavelength of radio wave > wavelength of light wave >wavelength of x Ray wave

And you can also write as

Frequency of X Ray wave > frequency of light wave > frequency of radio wave
