Answer 1

Given:

The temperature in Baguio City = 20°C

To find:

Speed of sound in air in Baguio City

Solution:

We know that velocity of sound in air at 273K (0°C)= 331m/s

Also, the speed of light is directly proportional to temperature

With every 1°C rise in temperature, the speed of light increases by 0.6m/s

So, speed of sound at temperature T=

331m/s + (0.6m/s/℃) . T

In the given question, T= 20℃

So speed of sound=  331m/s + (0.6m/s/℃) X 20℃

= 331m/s + (12m/s)

v= 343m/s

Therefore, the speed of sound at 20℃ is approximately 343 m/s.

Answer 2

Speed of sound in this air is 343 m/s.

• Particle-to-particle interaction causes a pressure disturbance to propagate across a medium as a sound wave. In order to move energy through the medium, each disturbed particle exerts a force on the next neighbouring particle behind it. This causes that particle to become disturbed from rest. A sound wave's speed is determined by how quickly the disturbance is transferred from particle to particle, much like any other wave. Speed is the amount of movement a disturbance makes per unit of time, whereas frequency is the number of vibrations a single particle makes per unit of time.
• Any wave's speed is determined by the characteristics of the medium it travels through. Inertial characteristics and elastic properties are typically the two primary categories of properties that influence wave speed. The tendency of a material to hold its shape and not deform when a force or stress is applied is referred to as an elastic property.
• The characteristics of the air, primarily the temperature and to a lesser extent the humidity, determine the speed of a sound wave in air.

Now, according to the given information, the atmospheric temperature in Baguio City is 20 ℃.

Then, speed of sound in air = v = 331 + (0.6 ) × T, where T here is 20.

Then, v = 331 + (0.6 ) × 20 = 343 m/s.

Hence, speed of sound in this air is 343 m/s.
