Assertion (A): A white light on passing through prism splits into its component colours as such that the red light emerges nearest to the base of the prism. Reason (R): Wavelength of red light is more than other component colours and hence, red light deviates least.?

Assertion (A): A white light on passing through prism splits into its ...
Explanation:
When a beam of white light passes through a prism, it gets refracted and splits into its component colours. This phenomenon is called dispersion. The different colours in the white light have different wavelengths, and hence, they get refracted by different angles.
Reason for Assertion (A):
The assertion is true. When white light is passed through a prism, the red light emerges nearest to the base of the prism. This is because the refractive index of the prism for red light is the least. Hence, the deviation of red light is the least, and it emerges closest to the original direction of the incident beam.
Reason for Reason (R):
The reason is also true. The wavelength of red light is the longest in the visible spectrum, and hence, it bends the least while passing through the prism. On the other hand, the wavelength of violet light is the shortest, and it bends the most. This is why the violet light emerges farthest from the base of the prism.
Conclusion:
Hence, both the assertion and the reason are true, and the reason explains the assertion.
