The time period of the crystal motion is equal to 1.06 ×10⁻⁵ seconds.
The time period of oscillation of a wave can be defined as the time taken by any element to complete one oscillation.
The time period for a wave can be represented as follows:
T = 2π/ω
The frequency defines as the number of completeoscillations made by any wave element per unit of time. The frequency can be defined as a parameter that explains the rate of oscillation and vibration.
The relation between the frequency and the time period can be written as:
f = 1/T
Where f is the frequency of the wave and T is the time period of the wave.
Given, the frequency with which the crystalvibrates, f = 93621 Hz
The time period (T) of the crystals motion can be determined as:
T = 1/f = 1/ 93621
T = 1.06 ×10⁻⁵ sec

Answer:
The velocity of the ball becomes half when the time period is doubled.
Explanation:
Let be the time period of the ball, be radius and be the velocity of the ball performing circular motion.
Now, for a circular motion, the velocity is given as:
From the above relation, we can conclude that, velocity is inversely proportional to time period if the radius is constant.
This means that if time period is increased, velocity will decrease and vice-versa.
So, if time period is doubled, the velocity will reduce by half. This can be verified mathematically also given below.
Divide by , we get
Here, are the new and old velocities.
So, it can be concluded that if the time period is doubled, velocity is reduced by half.
The wavelength and frequencyincrease (decrease) in proportion to energy levels. Short wavelengths have a higher energy than long wavelengths because of the link between wavelength and frequency, which dictates that the higher the frequency, the shorter the wavelength.
Energy is defined as the capacity of a physical system to perform work.
Wavelength is related to energy and frequency by
E = hν = hc/λ,
where E = energy, h = Planck's constant, ν = frequency, c = the speed of light, and λ = wavelength
The number of waves that pass a specific place in a predetermined period of time is known as the wave frequency. The hertz is the wave frequency SI unit (Hz)
The distance between two successive crests or troughs of a wave is known as its wavelength. It is calculated using the wave's direction.
The wavelength and frequencyincrease (decrease) in proportion to energy levels.
