Question

Observe the following diagram. If the speed of the wave stays the same and the period decreases, what wave property would also decrease?

A.) Wavelength
B.) Frequency
C.) Wave height
D.) Amplitude

Answer 1

I guess the wavelength as the period becomes smaller the wavelength will decrease and frequency will increase all the rest should remain the same

Hope that helps

Answer 2

The right answer is A.) Wavelength

The wavelength is designated by λ and its unit is the meter [m]. It represents the distance between 2 zones of overpressure.

The wavelength is the spatial-equivalent of the time period (at equal speed). Indeed, the wavelength is the distance traveled by the wave during a period. So these two are influenced in the same way, if one increases, the other increases and vice versa.
