Question 3
HFigure shows part of the electromagnetic spectrum. Three of the groups have been replaced by the letters P, Q and R.
Figure: Part of the electromagnetic spectrum, in order of increasing frequency
a.[2]
Write the names of the groups labelled P and R.
b.[3]
A wave in group Q has a wavelength of 5.0 × 10-7 m. Electromagnetic waves travel through a vacuum at 3.0 × 108 m/s. Calculate the frequency of this wave. Use the Physics Equations Sheet.
c.[1]
A different electromagnetic wave has half the wavelength of the wave in part (b). Describe the frequency of this different wave.
