Wavelength of violet colour is……… wavelength of red colour. Therefore, `mu_v` …………`mu_r`. Hence, `delta_v` ………. `delta_r`.

Violet : lowest wavelength :: Red : ___________

Wavelength of red colour is approximately how many times the wavelength of violet colour ?

Which colour of light has the shorter wavelength-red or violet ?

The wavelength of green colour in air and violet colour in water are 5381 overset (@)(A) and 3042 overset (@)(A) respectively . If the wavelength of green colour in water is the same as the wavelength of violet colour in air , find its value . (Assume that refrective index for green and violet colour is approximately same)

The wavelength of green colour in air and violet colour in water are 5381 Å and 3042 Å respectively. If the wavelength of green colour in water is the same as the wavelength of violet colour in air, find its value. (Assume that refractive index for green and violet colour is approximately same)

Assertion (A): The light of violet colour deviates the most and the light of red colour the least, while passing through a prim. Reason (R):The refractive index in highest for red light and lowest for the violet light.

Arrange these colours in an increasing order of wavelength : red, violet, yellow, green
