What happens to the speed wavelength and frequency when sound wave passes from cool air into warmer air?
When a sound wave passes from cool air to warmer air, its speed increases due to the higher temperature in the warmer air, resulting in a shorter wavelength. This increase in speed causes the frequency of the sound wave to remain constant, as frequency is determined by the source of the sound rather than the medium it travels through.
What happens if you are travelling faster than the speed of sound?
When travelling faster than the speed of sound (supersonic speed), a sonic boom is created. This is a loud noise produced when an object passes through the air at a speed greater than the speed of sound. It can be disruptive and can lead to regulations on supersonic flight over populated areas.
Refraction of a sound wave occurs when a wave passes at an angle from one medium into another in which the of the wave is different?
Refraction of a sound wave occurs when it passes through media with different densities, causing a change in its speed and direction. This change in speed leads to the bending of the sound wave at the interface between the two media.
Would the pilot of an airplane breaking the sound barrier hear a sonic boom?
No, the pilot of an aircraft breaking the sound barrier would not hear the sonic boom because the aircraft is traveling at the same speed as the sound waves it creates. The sonic boom is heard on the ground as the aircraft passes overhead.
How is sound refracted?
Sound is a wave (of energy) in a medium [solid,liquid, or gas] (a compression wave in fact), therefore it is refracted by any change in the medium AND by the fact that it is never coherent (it never travels in only a straight line).
What happens to the speed of sound when it passes through a solid?
It is reflected because of the way the particles are transmited
What happens to the speed of the light when it passes from air into glass?
The speed decreases.
What happens to the speed wavelength and frequency when sound wave passes from cool air into warmer air?
When a sound wave passes from cool air to warmer air, its speed increases due to the higher temperature in the warmer air, resulting in a shorter wavelength. This increase in speed causes the frequency of the sound wave to remain constant, as frequency is determined by the source of the sound rather than the medium it travels through.
What happens to speed of sound in air when sound get louder?
The loudness of the sound has no effect on its speed.
When is the speed of sound near the ground less than the speed of sound higher up?
If the speed of sound near the ground is less than the speed of sound higher then in this special case the temperature at the ground must be less than the temperature higher up. Usually the temperature at the ground is warmer than the temperature high up in the sky. The speed of sound changes mainly with the temperature.
What happens if you are travelling faster than the speed of sound?
When travelling faster than the speed of sound (supersonic speed), a sonic boom is created. This is a loud noise produced when an object passes through the air at a speed greater than the speed of sound. It can be disruptive and can lead to regulations on supersonic flight over populated areas.
What happens when light passes into a material where the speed of light is lower?
It moves at a slower speed!
What happens to the speed of light as passes from water to air?
It increases.
How does sound intensity decrease due to density of a substance it passes through?
The speed of sound and density are related as . So the greater the density the speed of sound decreases.
What strange thing happens to the Concorde when it flies faster than sound?
When the Concorde flies faster than sound, it experiences a shockwave known as a sonic boom. This causes a loud and distinctive noise to be heard on the ground as the aircraft passes overhead. The sonic boom is caused by the rapid displacement of air molecules as the aircraft exceeds the speed of sound.
What happens to an aircraft's speed when it dives to ground?
It increases.
Refraction of a sound wave occurs when a wave passes at an angle from one medium into another in which the of the wave is different?
Refraction of a sound wave occurs when it passes through media with different densities, causing a change in its speed and direction. This change in speed leads to the bending of the sound wave at the interface between the two media.
