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

Answer:

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

Explanation:

It is given that,

Frequency of the electromagnetic wave, $f=1.90\times 10^{14}\ Hz$

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

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

$\lambda=\dfrac{v}{f}$

$\lambda=\dfrac{205\times 10^8\ m/s}{1.90\times 10^{14}\ Hz}$

$\lambda=0.000107\ m$

$\lambda=0.107\ mm$

Hence, this is the required solution.
