If the string is 7.6 m long, has a mass of 34 g , and is pulled taut with a tension of 15 N, how much time does it take for a wave to travel from one end of the string to the other

The wave takes 0.132 seconds to travel from one end of the string to the other.

Explanation:

The velocity of a transversal wave () travelling through a string pulled on both ends is determined by this formula:

Where:

- Tension, measured in newtons.

- Length of the string, measured in meters.

- Mass of the string, measured in meters.

Given that , and , the velocity of the tranversal wave is:

Since speed of transversal waves through material are constant, the time required () to travel from one end of the string to the other is described by the following kinematic equation:

If and , then:

The wave takes 0.132 seconds to travel from one end of the string to the other.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
