When light travels from one medium to another which factors changes?

direction changes.


Which property of light will change when the medium of propagation changes?

The speed.


Why frequency of light never change when light changes medium?

When light enters another medium it changes speed, but thewavelength changes correspondingly so that the frequency does not change. For example, if light enters a medium where its speed is cut in half, then the wavelength will also be reduced by half.


When light waves enter a new medium and bend what occurs?

When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of refraction.


How does the wavelenth changes when light travel from ane optical medium to another optical medium?

Diamond (solid)


How is refraction linked to light speed?

When light enters a different medium (refracts), its speed changes.


Is it true that speed of light changes with medium?

Yes. The speed of light in a vacuum (or space) is 3x10^8 m/s. Light will travel slower in any other medium.


What will lowering the pH of a medium do to the angle of refraction of light?

Lowering the pH of a medium, such as a liquid, will not have a direct effect on the angle of refraction of light. The angle of refraction of light is primarily determined by the refractive index of the medium, which is not inherently influenced by pH changes. However, extreme changes in pH may induce changes in the optical properties of the medium, potentially leading to alterations in the refraction of light.


Does the speed of light changes when it goes from rarer medium to denser medium having angle of incidence equal to 0?

The speed of light changes when it goes from one medium to another one with a different index of refraction. The angle of incidence doesn't influence the change in speed.


What causes refraction-?

Refraction is caused by light crossing from one medium to another.


What is the effect on the speed of light when temperatures rise in the medium?

When temperature rises, the density of the medium changes. Speed of light through a medium is inversely proportional to the density of medium. So when the temperature increases, the density decreases and the speed of light in that medium increases. Note that this is the indirect effect of temperature. If light is travelling through vaccuum , then the temperature will have no effect on the speed of light.


What is the bending of light rays when they travel from one medium to another?

this process is called refraction and usually happens when light changes medium eg from air to water or into a prism :)
