Question

"As a boat travels across the lake it passes a fixed point causing waves which travel at 8 waves per second and each wave is two meters apart. Calculate the waves speed?"

Answer 1

The speed of the waves created as the boat passes by can be calculated by multiplying the frequency (8 waves per second) by the wavelength (2 meters), resulting in a wave speed of 16 meters per second.

Step-by-step explanation:

This is asking about calculating the speed of water waves as a boat passes a fixed point. The waves travel at 8 waves per second (frequency), and each wave is 2 meters apart (wavelength). To find the wave's speed, you multiply the frequency by the wavelength. The formula for wave speed (v) is v = frequency (f) × wavelength (λ). In this case: Frequency (f) = 8 waves per second, Wavelength (λ) = 2 meters. Therefore, you calculate the wave's speed as follows: v = 8 waves/second × 2 meters/wave = 16 meters/second. So, the speed of the waves is 16 meters per second.
