Answer:
[tex]Frequency=2.88\times 10^{14}\ s^{-1}[/tex]
Explanation:
The relation between frequency and wavelength is shown below as:
[tex]c=frequency\times Wavelength [/tex]
c is the speed of light having value [tex]3\times 10^8\ m/s[/tex]
Given, Wavelength = 1040 nm
Also, 1 m = [tex]10^{-9}[/tex] nm
So,
Wavelength = [tex]1040\times 10^{-9}[/tex] m
Thus, Frequency is:
[tex]Frequency=\frac{c}{Wavelength}[/tex]
[tex]Frequency=\frac{3\times 10^8}{1040\times 10^{-9}}\ s^{-1}[/tex]
[tex]Frequency=2.88\times 10^{14}\ s^{-1}[/tex]
