VERY EASY QUESTION. WILL MARK BRAINLIEST If the speed of a wave increases but the frequency remains the same, what must be true of its wavelength?

The wavelength will decrease.
The wavelength will fluctuate wildly.
The wavelength will increase.
The wavelength will stay the same.

 (A)

Explanation:

increase in frequency will reduce the wavelength of the wave to keep the velocity constant (v=nu x lambda) and vice versa
