Answer:
a) destructive interference occurs
Explanation:
Given that two waves are traveling towards each with same magnitude of amplitude .
As we know that when two waves are superimpose then
1. If they are traveling in the same direction then the resultant wave amplitude is higher than the amplitude of any the given wave and this is known as constructive interference.
2. If they are traveling in the opposite direction then the resultant wave amplitude is lower than the amplitude of any the given wave and this is known as destructive interference.
So the answer is a.
a) destructive interference occurs
Answer is A, Sound waves will travel faster on warm air because collisions of molecules of air in warm air are greater.
