question: What can we learn about a wave by finding the product of the wavelength and frequency?
distractor3: type
distractor1: decibels
distractor2: volume
correct_answer: speed
support: The speed of a wave is a product of its wavelength and frequency. Because all electromagnetic waves travel at the same speed through space, a wave with a shorter wavelength must have a higher frequency, and vice versa. This relationship is represented by the equation:.
