State the cause of dispersion of white light passing through a glass prism. How did Newton show that white light of sun contains seven colours using two identical glass prisms. Draw a ray diagram to show the path of light when two identical glass prisms are arranged together in inverted position with respect to each other and a narrow beam of white light is allowed to fall obliquely on one of the focus of the first prism.
What happens when a ray of ordinary light is passed through a triangular glass prism?
What is a rainbow? What are the two conditions necessary for the formation of a rainbow in the sky?
Out of the following, the colour of light having the maximum wavelength is:
(a) violet
(b) indigo
(c) green
(d) orange
State the speed of light in (a) air, (b) water, and (c) glass
A ray of white light falls on a prism. Draw a ray diagram to show that the prism disperses the white light.
Complete the ray diagram given below to show the nature of light produced on the screen.
The completed ray diagram is as shown below:
Write the range of wavelength of the infrared spectrum.
The periscope is an optical device with a polished surface that reflects the light falling on it.
The dispersive powers of flint glass and crown glass are 0.053 and 0.034, respectively and their mean refractive indices are 1.68 and 1.53 for white light. Calculate the angle of the flint glass prism required to form an achromatic combination with a crown glass prism of refracting angle 4°:
