Question

the wavelength of an electromagnetic wave is 0.01 A°. calculate the frequency, assuming velocity of wave =3*10^8m/s.
​

Answer 1

Answer:

X−rays is a form of electromagnetic radiation. Most X−rays have a wavelength ranging from 0.01to10 nm, corresponding to frequencies in the range 30 petahertz to 30 exahertz (

3×10 16

20

Hz) and energies in the range 100eVto100keV.

The formula for frequency, when given wavelength and the velocity of the wave, is written as:

f=

λ

v

.

In this formula,

f represents frequency, v represents the velocity of the wave, and λ represents the wavelength of the wave. X-ray is part of the Electro-magnetic wave spectrum. All waves of this spectrum travel with the same speed of

3×10 8

.

Hence, the frequency of x-rays is

Answer 2

Answer:

Explanation:

Velocity=freq×wavelength

3×10^8= freq× 0.01×10^-10m

3x10^20= freq
