Question

What is the wavelength of a red laser with a frequency of 4.3 x 10^54 Hz

Answer 1

The wavelength is 7.0x10⁻⁴⁷ m

Step-by-step explanation:

To solve this problem we can use the equation:

• c = λ*v

Where:

• c is the speed of light (3x10⁸m/s)

• λ is the wavelenght (in m)

• v is the frequency (in Hz)

We put the data given by the problem:

• 3x10⁸ m/s = λ * 4.3x10⁵⁴ Hz

And solve for λ:

• λ = 7.0x10⁻⁴⁷ m
