How do you calculate frequency of light?

Answer 1

I'm assuming you have been given some further information. Otherwise you can only give a range depending on which area of the spectrum it's in.

The most common question is using c = #f.lambda# where c is the speed of light in a vacuum and #lambda# is the wavelength. You are given velocity and wavelength.

In the second, which is more frequently used, energy and frequency are connected (E = h.f), and once more, a value for h, Planck's constant, and the photon energy, E, are provided.

The frequency of light can be calculated using the formula:

Frequency = Speed of light / Wavelength

Where the speed of light is approximately 3.00 x 10^8 meters per second (m/s) in a vacuum, and the wavelength is measured in meters.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
