Solve Exercise 1 Page 45 Physics 12 Textbook
Problem Statement:
What is the phenomenon of wave interference?
Solution:
Wave interference phenomenon is when two waves combine, resulting in some points where they always reinforce each other, and some points where they completely cancel each other out.

Solve Exercise 4 Page 45 Physics 12 Textbook
Problem:
State the conditions for interference.
Solution:
Conditions for interference phenomenon: Two wave sources must be coherent, meaning: they must oscillate in the same direction, with the same frequency (or wavelength), and have a constant phase difference over time.
A. intersection of two waves at a point in the medium.

Solution for Exercise 7 on page 45 of Physics 12 Textbook
Problem:
In the experiment in figure 8.1, the wave velocity is 0.5 m/s, and the required frequency is 40Hz. Calculate the distance between two consecutive interference maxima on segment S1S2 .
Solution:
Solution for Problem 8 on Page 45 of Physics 12 Textbook
Problem:
In the experiment shown in figure 8.1, the distance between two points S1 and S2 is d = 11cm. With the vibrating source, we observe that points S1 and S2 remain almost stationary, and there are 10 stationary points between them. Given the frequency of the vibrating source is 26 Hz, calculate the wave velocity.
Solution:
Similarly to the solution for Exercise 7, we find: The distance between two consecutive interference maxima is half of a wavelength. Similarly, we have:
