If one wave of 10 m amplitude meets constructively with another of amplitude 20
m, what is the new amplitude?
20 m
30 m
200 m
10 m

Respuesta :

Answer:

B. 30m

Explanation:

This is because when a wave interferes constructively with another wave, they will add since constructive relates to joining or building up.

So, 10m + 20m equals a 30m wave.
