Question

The wavelength of red light is 800nm. Find the frequency. Speed of light is 3x10 to the power 8m/s

Answer 1

Answer: here is the answer

Explanation:

Answer 2

Given ,

• Speed of light = 3 x 10^8 m/s
• Wavelength of the light = 800 nm

To Find frequency of the light = ?

We can use the formula ,

• Frequency = Speed / Wavelength
• Frequency = 3 x 10^8 m / 800 nm s
• Frequency = 3 x 10^8 m / 8 x 10^-7 m s
• Frequency = 3 x 10^15 / 8 s
• Frequency = 0.375 x 10^15 sec^-1
• = 0.375 x 10^15 Hz.
