Question

What is the frequency of a particular type of radiation in hertz given that the wavelength is 4.40 times 10

Answer 1

Answer:

$Frequency=6.81\times 10^{14}\ Hz$

Explanation:

The relation between frequency and wavelength is shown below as:

$c=frequency\times Wavelength$

c is the speed of light having value $2.998\times 10^8\ m/s$

Given, Wavelength = $4.40\times 10^{2}$ nm

Also, 1 m = $10^{-9}$ nm

So,  

Wavelength = $440\times 10^{-9}$ m

Thus, Frequency is:

$Frequency=\frac{c}{Wavelength}$

$Frequency=\frac{2.998\times 10^8}{440\times 10^{-9}}\ Hz$

$Frequency=6.81\times 10^{14}\ Hz$
