Question

find wavelength in nm whose frequency is 1.5×10¹⁴​

Answer 1

Answer:

Step-by-step explanation:

The frequency of wave is 1.5 x $10^{14}$ Hz

Now,  we have the formula v = f λ

To complete this question, we require the speed of light

When we get the speed, we can calculate the wavelength in std metres unit

Then the value has to be multiplied by $10^{9}$ to get answer in nanometres

I hope this helps

Happy PHYSICS !!!
