Explanation
What happens: Sounds repeat their cycles over time.
Key idea: Find the common multiples of the frequencies (or periods).
Frequencies heard at: Years that are multiples of the Least Common Multiple (LCM) of 300, 400, and 500, which relates to the years 100, 200, 300, 400, 500 (all multiples of 100).

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Sound needs a medium (like air, water, or solids) to travel because it moves by vibrating particles.
In a vacuum, there are no particles to vibrate, so sound cannot travel and no sound can be heard.
600 ft/sec

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The velocity of sound is calculated using the formula:
Velocity=Frequency×Wavelength
Given:
Frequency = 300 Hz
Wavelength = 4 ft
Velocity=300×4=1200 ft/sec
Volume of the room
Surface materials (absorption)
Number of people in the room
Frequency of the sound
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Reverberation time is mainly influenced by:
While absorption can vary slightly with frequency , the frequency itself is not a primary c ontrolling factor of reverberation time.
Transverse wave motion
Electromagnetic waves
Longitudinal wave motion
Circular wave motion
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
In longitudinal waves, the particles of the medium (air molecules, in this case) vibrate back and forth in the same direction as the wave is moving.
This is how sound propagates through gases like air.
Laplace also corrected Newton's theory by including the effect of adiabatic compression, improving the accuracy of the speed of sound calculation in air.
