Question

6
/3 - 2
rationalise the denomimator​

Answer 1

$\bold{ \frac{6}{3 - 2} \: \: \: \: \: rationalise}$

$= > \frac{6}{3 - 2} \times \frac{3 + 2}{3 + 2}$

$= > \frac{6(3 + 2)}{3 - 2}$

$= > \frac{18 + 12}{1}$

$= > 30$

We have studied about refraction through rectangular slab in previous chapter. Refraction through Prism is slightly different from it in a sense that the direction of emergent ray is different than the direction of incident ray, in case of prism.

We have studied about refraction through rectangular slab in previous chapter. Refraction through Prism is slightly different from it in a sense that the direction of emergent ray is different than the direction of incident ray, in case of prism. This in turn leads to a pleasant phenomenon called Dispersion.
