can you help me with these astronomy questions, I am totally lost?

Question

11. Calculate the frequency of yellow light if its wavelength is 600 x 10^-9 m. Show all the steps used in your calculation.

12. Calculate the wavelength of radio waves if their frequency is 5 x 10^6 Hz. Show all the steps used in your calculation.

Answer 1

The formula is simple:

wavelength = speed-of-light / frequency

OR (same thing just re-arranged)...

frequency = speed-of-light / wavelength

In this case:
- frequency is in Hertz
- wavelength is in meters
- speed-of-light is 2.998*10^8 meters/second

The formulas are simple, I'm sure you can do the simple math.
