A beam of light has a wavelength of 506 nanometers. What is the frequency of the light? What color is the light?

Answer 1

I found: #5.9xx10^14Hz#, Cyan.

You can find the frequency #nu# from:
#c=lambda*nu#
where:
#lambda=506xx10^-9m# is the wavelength;
#c=3xx10^8m/s# is the speed of light in vacuum.
So:
#nu=c/lambda=(3xx10^8)/(506xx10^-9)=5.9xx10^14Hz#

It should be Cyan (#506 nm#):

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.
