Wired Faculty App

A thin glass prism (μ =15) in the position of minimum deviation deviates the monochromatic light ray by 10^o, the refracting angle of prism is

20^o

10^o

30^o

45^o

Solution

20^o

When a narrow beam of sunlight, is incident on a glass prism the emergent light is seen to be consisting of several colours. There is actually a continuous variation of colour, but broadly in seven colours (acronym VIBGYOR)

The phenomenon of splitting of light into different colours known as dispersion.

$Given : - δ_{m} = 10^{o}, μ = 15 For a thin prism of minimum deviation δ_{m} = (μ - 1) A or A = \frac{10}{0.5} = 20^{o}$
