What happens when tension is doubled?

What happens when tension is doubled?

The velocity of a travelling wave in a stretched string is determined by the tension and the mass per unit length of the string. So, if we double the tension the speed will increase 1.41 times or root (2) times.

Why is velocity not proportional to wavelength?

The greater the linear mass density, the slower he wave speed. The speed of any wave is only dependent on the medium through which it travels. That is why the frequency and wavelength are inversely proportional.

What is the relationship between the speed of light frequency and wavelength?

The relationship between the frequency (the number of wave crests that pass by a certain point in a given amount of time) and wavelength for electromagnetic waves is defined by the formula, c = λ f, where c is the speed of light, λ the wavelength in meters, and f equals the frequency in cycles per second.

Does wavelength depend on medium?

Wavelength depends on the medium (for example, vacuum, air, or water) that a wave travels through. A sound wave is a variation in air pressure, while in light and other electromagnetic radiation the strength of the electric and the magnetic field vary. Water waves are variations in the height of a body of water.

Is refractive index dependent on wavelength?

The refractive index of a material depends on the optical frequency or wavelength; this dependency is called chromatic dispersion.

Does photon energy depend on medium?

To awnser your original question yes, wavelenght of “photons” depend on the medium, it is just that light in a medium is a bit more complicated than just a photon. Only in vacuum light travels without disturbances.

What causes light to slow down in a medium?

Light moves slower through denser media because more particles get in its way. Each time the light bumps into a particle of the medium, the light gets absorbed which causes the particle to vibrate a little and then the light gets re-emitted.
