Refraction is the bending of light as it passes through different mediums, such as air, water, or glass. This bending occurs due to the change in speed of light as it travels through these mediums.
The refraction of any light wavelength can be calculated using Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities of light in the two mediums. In this case, the angle of incidence and the velocity of light in air are known, and the angle of refraction can be calculated to determine the refraction of red light wavelength 750nm.
The angle of incidence is the angle at which light rays hit the boundary between two mediums. In this case, it is the angle at which the red light wavelength 750nm hits the boundary between air and another medium, such as water or glass.
The amount of refraction of red light wavelength 750nm will differ in different mediums due to the difference in their refractive indices. Refractive index is a measure of how much a medium can bend light, with higher refractive indices resulting in more bending. Therefore, the refraction of red light wavelength 750nm will be greater in a medium with a higher refractive index, such as glass, compared to a medium with a lower refractive index, such as air.
The refraction of red light wavelength 750nm is important because it allows us to understand the behavior of light as it travels through different mediums. This knowledge is crucial in fields such as optics, astronomy, and meteorology. It also has practical applications, such as in the design of lenses and mirrors for various optical instruments.
