Waves

What is the formula for the velocity of waves

and the other formula is

v = f*⋌

where,

v → Velocity of the wave

f → Frequency

⋌ → Wavelength

What is the formula for the velocity of a particle

What is the formula that relates the velocity of the particle and that of the wave?

What is the formula for the wave differential equation?

What is frequency? what does it depend upon?

The number of complete cycles or oscillations a wave (or object) makes in one second. It only depends upon the source.

What is the formula for the speed of a transverse wave?

Where,

T → Tension

μ → Mass per unit length of the string

In which cases is acceleration taken as constant?

Here are the cases :-

What is the formula for the speed of longitudinal waves in solids, liquids and gases

For solids:- √ɣ/ρ

For liquids/liquids:- √ß/ρ

What are the values and the different parts of the spectrum of frequency called

f < 20 hz → infrasonic waves

20 hz <= f <= 20 k Hz → Audible waves

f >= 20 k Hz → ultrasonic

What is the value that Newton got from his speed of waves? What was the actual value that was obtained after the experiments?

What is the formula for the relation between pressure and amplitude?

k → Wavenumber

What is the intensity of a wave? What is its formula?

It is the power per unit area

What is the formula for the loudness of a wave?; What is the value of the reference intensity?

Where,

I_o → Reference intensity → 10^-12 watt/m²

L→ Loudness

Bel → A unit of measurement

What is the value of 1 Bel?

1 bel = 10 decibels
