I. The colour of light depends on its frequency II. When white light is dispersed by a triangular prism, yellow is deviated more than green III. Rainbows are formed when rains fall heavily. Which of the above statements is/are correct about dispersion and colours?
If the critical angle for a glass–air boundary is 45º, what is the refractive index of the glass?
From the diagram above, the sine of the angle of refraction in glass is
What colour has the lowest frequency in the spectrum of white light?
Given that SQ = 10cm and SR = 6cm, the refractive index of the block of glass shown in the above figure is
