Speed of light wavelength equation [ENDORSED]

[Lauryn Jordan 1F]

When do you use the c = wavelength x frequency?

[Matthew 1C]

since the value of c is constant, being the speed of light, you can use the equation to solve for either wavelength of frequency, depending on what the given values are

[Ayona Sengupta]

Sometimes you might also need to rearrange and plug this formula into a larger question/different formula. For example, you might rewrite E=hv to E=hc/lambda.

Most commonly I think we have been using the equation in the form wavelength= c (3.0 x 10^8)/ frequency to solve for the wavelength. I feel like that is the most common form of the equation that we have seen.

Since the value of c is a constant should we memorize it for exams or will the its value be provided during?
