Question

15 multiple choice 2 points compared to the period of a wave of red light the period of a wave of green light is less greater the same

Explanation:

The relationship between the period \(T\) and frequency \(f\) of a wave is \(T=\frac{1}{f}\). The frequency of green light (\(f_{green}\approx 5.6\times10^{14}\text{ Hz}\)) is higher than the frequency of red light (\(f_{red}\approx 4.3\times 10^{14}\text{ Hz}\)). Since \(T = \frac{1}{f}\), a higher frequency means a lower period.

Answer:

less
