Question

An electromagnetic wave of frequency 1.90 x 10^14 Hz propagates in carbon tetrachloride with a speed of 205 x 10^8m/s. What is the wavelength of the wave in carbon tetrachloride?

Answer 1

The wavelength of the wave in carbon tetra chloride is 0.107 mm

Step-by-step explanation:

It is given that,

Frequency of the electromagnetic wave,
`f=1.90* 10^(14)\ Hz`

Speed of wave in carbon tetra chloride,
`v=205* 10^8\ m/s`

We have to find the wavelength of the wave in carbon tetra chloride. It is given by :

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

`\lambda=(205* 10^8\ m/s)/(1.90* 10^(14)\ Hz)`

`\lambda=0.000107\ m`

`\lambda=0.107\ mm`

Hence, this is the required solution.
