The speed of a sound wave depends on what type of medium it is traveling through, and if that medium is a gas or liquid, a significant change in temperature can also affect its speed. In air, the speed at which sound travels is about 1 mile every 5 seconds at 32 degrees Fahrenheit, but the speed of a sound wave traveling through solid rock is about 18 miles every 5 seconds. Sound travels faster through a solid substance like rock because, unlike liquids or gases, the molecules in a solid are held close together
This depends on the tides on earth cause by the moon
Explanation: because tides occur daily
Wavespeed (V) = Frequency F x wavelength λ (V = F λ)
The wavespeed is the distance covered by a wave in one second. It is measured in metre per second, and represented by the symbol V. It is directly proportional to the wavelength and frequency
i.e Velocity (V) = Frequency F x wavelength λ
V = F λ
Assume wavelength (λ)= 20 m
Frequency = 10 Hz.
To get the wavespeed, use the formula
V = F λ
V = 20 metres x 10 hertz
V = 200 metres per second
Thus, the wave travels at a speed of 200 metres per second
1) designed to measure the difference in speed of light in different directions , 1887
1) This experiment was designed to measure the difference in speed of light in different directions and therefore find the speed of the ether.
2) was made in 1887
3) At that time it was assumed that it was the medium in which light traveled and it is everywhere
4) the speed of the wave depends on the characteristics of the medium where it travels,
for the one in a string depends on the tension and density
for an electromagnetic wave of the permittivity and permeability of the vacuum
5) In this type of interferometer the beam is divided into two rays
6) In his interrupter, he had to accurately measure the displacement of the fringes in a telescope, for which he had to minimize vibrations, he had problems in the movement of one of the arms, changes in temperature
7) In Michelsom's second experiment, the apparatus could measure 0.01 fringes by increasing the length of the arms by 11 m
8) The new interferometer floated on a bed of mercury
9) Couldn't measure any difference in speed of light in different directions
10) Physics was forced to eliminate the concept of ETHER
11) One of the principles of relativities that the speed of light is constant in all inertial efficiency systems
12) Michelson in 1907
13) It seems that Einstein did not know the results of this experiment
The wave impulse produced in the rope is likely to decrease. This is because there will be a damping effect. The downward effect of the rope has a damping effect on the rope. This means that the rope waves will be weaker or diminished by the time they get to the upper end of the rope. Thus, the wave magnitude decreases. In this way, the pulse or wave propagation on the rope decreases from down upwards.
The lower portion of the rope pulls down on the higher portions of the rope. Therefore, the tension in the rope increases as we move up the rope.What is the period of a wave if the wavelength is 100m and the speed is 200 m/s? ... Just like sound wave travels at a constant 340.29m/s in air, it does not change regardless.
The ratio between initial and final speed is 3:4
The speed of a wave is given by the wave equation:
v is the speed
f is the frequency of the wave
is the wavelength
In this problem, we have a wave with wavelength and initial frequency
So its speed can be written as
Later, its frequency changes to
Assuming that its wavelength has not changed, this means that its new speed is
By calculating the ratio between the two,
So, the ratio between initial and final speed is 3:4.
