Answer: The correct answer is option a.
Explanation:
To calculate the frequency of the ray, we use the formula:
[tex]\nu=\frac{c}{\lambda}[/tex]
where,
[tex]\nu[/tex] = Frequency of the ray = ? Hz
c = Speed of light = [tex]2.998\times 10^8m/s[/tex]
[tex]\lambda[/tex] = Wavelength of the ray = [tex]3.10\times 10^{14}m[/tex]
Putting values in above equation, we get:
[tex]\nu=\frac{2.998\times 10^8m/s}{3.10\times 10^{14}m}\\\\\nu=0.967\times 10^{-6}s^{-1}=0.967\times 10^{-6}Hz[/tex]
Hence, the correct answer is Option a.
