Final answer:
The period and frequency of light waves are inversely related; when one increases, the other decreases. The correct relationship is that a shorter period corresponds to a higher frequency.
Step-by-step explanation:
The relationship between period and frequency of light waves is that they are inversely related. When the period of a light wave increases, its frequency decreases, and vice versa. Considering this, the correct statement describing the relationship would be: In wave B the period is shorter, and the frequency is greater than in wave A. Hence, the correct answer is C) In wave B the period is shorter and the frequency is greater than in wave A.
