Answer:a) The formula for calculating the time period of a simple pendulum is:

T = 2π√(l/g)

where T is the time period in seconds, l is the length of the pendulum in meters, and g is the acceleration due to gravity in meters per second squared.

b) Three factors that affect the time period of a simple pendulum are:

Length of the pendulum: The time period of a pendulum is directly proportional to the square root of its length. This means that as the length of the pendulum increases, the time period also increases.

Mass of the pendulum: The mass of the pendulum does not affect the time period of a simple pendulum, as long as the mass is concentrated at the end of the pendulum.

Acceleration due to gravity: The time period of a pendulum is inversely proportional to the square root of the acceleration due to gravity. This means that as the acceleration due to gravity increases, the time period decreases. The acceleration due to gravity varies depending on the location on Earth, but it is approximately 9.8 m/s^2.

Explanation:

Answer:

The formula for time is: – T = 1/f, where T is period and f is frequency.

λ= c / f, where c is wave speed (m/s) and f is frequency (Hz).

Explanation:

(b) The time period of the simple pendulum depends upon the length of the pendulum and also to some extent it depends upon the degree of the amplitude. That is the width of the pendulum's swing. In general, the time period of a pendulum means one complete cycle that is one complete left swing and right swing.
