Since a string pulse get amplified when it enters a less dense medium such as from the thick heavy rope to a lighter string, why does not light do the same?
Yes, a light pulse can experience amplification when it travels from a more dense medium to a less dense medium. This phenomenon is known as refraction, and it occurs because light travels at different speeds in different materials.
When light is refracted, the direction of the light beam changes as it travels through a different medium. This change in direction can concentrate or spread out the light, leading to a change in intensity. In some cases, the light may become more intense, while in others, it may become less intense.
No, in a vacuum, there are no particles to interact with the light pulse and cause amplification. Refraction and amplification require a medium to occur.
The angle of incidence, or the angle at which the light pulse enters the new medium, plays a role in determining the amount of amplification that occurs. A steeper angle of incidence can result in a greater change in direction and, therefore, a greater amplification of the light pulse.
Yes, the wavelength of light can also impact the amount of amplification that occurs when it enters a less dense medium. This is because different wavelengths of light interact with materials in different ways, leading to variations in refraction and amplification.
