What happens to the speed wavelength and frequency when sound wave passes from cool air into warmer air?
the speed and wavelength increase but the frequency stays the same
When speed passes from one medium wave to another what happens?
it changes in velocity
What happens to light as it passes through different mediums?
Its speed and wavelength change.
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 as a medium cools?
it slows down
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 wavelength and frequency when sound wave passes from cool air into warmer air?
the speed and wavelength increase but the frequency stays the same
What happens to the speed of the light when it passes from air into glass?
The speed decreases.
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 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 if you are driving a car at the speed of light and you cut your headlights on?
They'll leave your car at the speed of light, and when that light passes anybody, they'll measure the speed of the light as it passes them to be the speed of light.
When speed passes from one medium wave to another what happens?
it changes in velocity
What happens to light as it passes through different mediums?
Its speed and wavelength change.
