When do you use the c = wavelength x frequency?

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

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?
