Questions for 17.3.11

Calculate wavelengths using the given frequencies in the formula in the powerpoint we used last week:

1. 1000 Hz
2. 3500 Hz
3. 70 Hz
4. 563 Hz

Rearrange the formula wavelength = wave speed / frequency to calculate the frequencies of the following wavelengths:

1. 200nm
2. 3.5m
3. 1cm
4. 60cm

Remember that wavelengths always need to be in meters, and  frequency is always measured in hertz.
