A sound wave has a frequency of 620 Hz in air
and a wavelength of 0.5 m.
What is the temperature of the air? As-
sume the velocity of sound at 0°C is 327 m/s.
Answer in units of C.

The temperature of the air is -27°C

Explanation:

Given:

Frequency (f)=620 Hz

Wavelength (λ)=0.5 m

To Find:

Temperature of air = ?

Formula to be used:

Solution:

velocity at the current temperature v=fλ

Temperature of the air is given by the expression

Thus the temperature of the air is -27°C

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.
