Question
Based on the electromagnetic spectrum diagram provided on page 4, which of the following regions is associated with the longest wavelengths?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The diagram on page 4 shows that as you move from right to left along the wavelength axis (Wavelength (m)), the wavelengths increase. Gamma rays and X-rays are on the far right (smallest wavelengths), visible light is in the middle, and microwaves are to the left of visible light, indicating longer wavelengths than the other options, falling into the 3m range, which is much longer than 10^-8 to 10^-12 m for gamma/x-rays or 10^-7 for visible light.
Hint
Examine the 'Wavelength (m)' axis on the spectrum diagram and the positions of the different wave types.
