The work function is what we call the minimum energy that is required by an electron to leave the metal target in the photoelectric effect.
True, because people should reach their full potential within themselves and human psychologist should help those that need help to reach it.
Answer:
Explanation:
Let the amplitude of individual wave be I and resultant amplitude be 1.703 I . Let the phase difference be Ф in terms of degree
From the formula of resultant vector
(1.703I)² = I² + I² + 2 I² cosФ
2.9 I² = 2I² + 2 I² cosФ
.9I² = 2 I² cosФ
cosФ = .9 / 2
= .45
Ф = 63.25 .
The answer is A bc I did the quiz and I got it right
