In the formation of spectrum of white light by a prism:
which colour is deviated most?
What acts as tiny prisms in the formation of a rainbow?
The frequency range of visible light is from 3.75 × 1014 Hz to 7.5 × 1014 Hz. Calculate its wavelength range. Take speed of light = 3 × 108 m/s.
What is the cause of the dispersion of white light through a glass prism? Draw a ray diagram to show the path of light when two identical glass prisms are arranged together in an inverted position with respect to each other and a narrow beam of white light is allowed to fall obliquely on one of the faces of the prisms.
Which characteristic property of light is responsible for the blue colour of the sky?
Distinguish between an impure spectrum and a pure spectrum.
Write the range of wavelength of the ultraviolet spectrum.
______ colour is deviated the least in the spectrum of white light obtained with a glass prism.
A prism of refractive index `sqrt2` and refracting angle A produces minimum deviation δm of a ray on one face at an angle of incidence 45°, The values of A and δm are, respectively ______.
