Question 1:

What happens when two waves interfere constructively?

Explanation: The correct answer is B) They amplify each other. When two waves interfere constructively, their amplitudes add up, resulting in an amplified wave. This occurs when the crests of one wave align with the crests of the other wave.

Question 2:

What happens when two waves interfere destructively?

Explanation: The correct answer is A) They cancel each other out. When two waves interfere destructively, their amplitudes subtract from each other, resulting in a wave with reduced or zero amplitude. This occurs when the crests of one wave align with the troughs of the other wave.

Question 3:

What is the phenomenon called when two waves of equal frequency and amplitude are perfectly aligned?

Explanation: The correct answer is C) Standing wave. When two waves of equal frequency and amplitude are perfectly aligned, they form a standing wave. This occurs when the crests and troughs of the waves align, creating stationary points with minimum or maximum amplitudes.

Question 4:

What is the result of the superposition of two waves with slightly different frequencies?

Explanation: The correct answer is A) Beats. When two waves with slightly different frequencies superpose, they create a phenomenon known as beats. This results in a periodic variation of amplitude, producing a beat frequency equal to the difference between the two wave frequencies.

Question 5:

What is the term for the overlapping of waves from different sources?

Explanation: The correct answer is B) Interference. Interference occurs when waves from different sources overlap and interact with each other. This can result in constructive or destructive interference, depending on the phase relationship between the waves.
