- The measured speed of sound and the measured speed of light.
Are the following statements true?
---------------------------------------------------------------
If a speaker and a listener are stationary with respect to the air, a listener will measure the speed of sound at about 343 m/s.
Since the speed of a sound wave in air is dependent only on the properties of the air, if a speaker is traveling toward a listener at 100 m/s, the listener will still measure the speed of the sound as 343 m/s.
If a listener is traveling toward a speaker at 100 m/s, the listener will measure the speed of the sound as 343 + 100 = 443 m/s.
---------------------------------------------------------------
In 1904. After Maxwell and before Einstein would it have reasonable to conclude:
If an emitter of light and an observer of light are stationary with respect to the ether, an observer of light will measure the speed of light at about 300,000,000 m/s.
Since the speed of an emitter of light is dependent only on the properties of the ether, if an emitter of light is traveling toward an observer of light at 100,000,000 m/s, the observer will still measure the speed of the light as 300,000,000 m/s.
If an observer of light is traveling toward a emitter of light at 100,000,000 m/s, the observer of light will measure the speed of the light as 300,000,000 + 100,000,000 = 400,000,000 m/s.
