Final Answer :
A
Explanation :
The frequency ( fff ) of light can be calculated using the formula f=cλf = \frac{c}{\lambda}f=λc , where ccc is the speed of light ( 3.0×108 m/s3.0 \times 10^{8} \, \text{m/s}3.0×108m/s ) and λ\lambdaλ is the wavelength of the light. Given λ=1.5×10−12 m\lambda = 1.5 \times 10^{-12} \, \text{m}λ=1.5×10−12m , f=3.0×1081.5×10−12=2.0×1020 s−1f = \frac{3.0 \times 10^{8}}{1.5 \times 10^{-12}} = 2.0 \times 10^{20} \, \text{s}^{-1}f=1.5×10−123.0×108=2.0×1020s−1 .
