A large magnification in an astronomical telescope can be achieved when the objective lens has a long focal length, and the eyepiece has a short focal length. This increases the ratio of the objective's focal length to the eyepiece's focal length, enhancing magnification. For more visit here: https:Read more

The angle of deviation differs for different colors of light because each color has a unique wavelength, leading to varying refractive indices in the glass prism. Shorter wavelengths, like violet, are refracted more, causing greater deviation, while longer wavelengths, like red, deviate less. For moRead more

The angle of minimum deviation decreases when violet light is replaced by red light. This is because red light has a longer wavelength, resulting in a lower refractive index for the glass prism. Consequently, red light undergoes less bending compared to violet light, reducing the angle of minimum deRead more

Why is the value of angle of deviation for a ray of light undergoing refraction through a glass prism for different colours of light?
The angle of deviation differs for different colors of light because each color has a unique wavelength, leading to varying refractive indices in the glass prism. Shorter wavelengths, like violet, are refracted more, causing greater deviation, while longer wavelengths, like red, deviate less. For moRead more

How does the angle of minimum deviation of a glass prism vary, if the incident violet light is replaced by red light? Give reason.
The angle of minimum deviation decreases when violet light is replaced by red light. This is because red light has a longer wavelength, resulting in a lower refractive index for the glass prism. Consequently, red light undergoes less bending compared to violet light, reducing the angle of minimum deRead more
