Q1) Two simple pendulums X and Y differ slightly in length. When set
swinging together, they gradually become out of step, but are back in
step each time X completes 100 oscillations. The length of Y differs
from that of X by approximately 1 part in 50. Why? Please explain in
details.

Q2) When a beam of light of intensity I and frequency f is shone on
the surface of a metal connected to earth, 200 electrons are rejected
from the surface per second. If a light beam of intensity 2I and
frequency 2f is used, the number of electrons ejected from the metal
per second will be still 200. Why? Please explain in details.
