Question

A flash lamp is placed at the center of a solid sphere of dense flint glass of radius 1.00 m. A second, identical flash lamp is placed at the center of a solid sphere of quartz also of radius 1.00 m. At the same instant both lamps are turned on, each producing a flash of white light (that is, light of all visible colors).

Using the graph shown, rank the times of the following events, from earliest to latest.

(i) The instant that violet light of vacuum wavelength 400 nm reaches the surface of the dense flint glass sphere

(ii) The instant that red light of vacuum wavelength 700 nm reaches the surface of the dense flint glass sphere

(iii) The instant that violet light of vacuum wavelength 400 nm reaches the surface of the quartz sphere

(iv) The instant that red light of vacuum wavelength 700 nm reaches the surface of the quartz sphere

Question 1 (1 point) A flash lamp is placed at the center of a solid sphere of dense flint glass of radius 1.00 m. A second, identical flash lamp is placed at the center of a solid sphere of quartz also of radius 1.00 m. At the same instant both lamps are turned on, each producing a flash of white light (that is, light of all visible colors). 1.8- Dense flint glass 1.7- Index of refraction Flint glass 1.6 Quartz Crown glass 1.5+ 400 500 600 700 Wavelength in vacuum (nm) Using the graph shown, rank the times of the following events, from earliest to latest. (i) The instant that violet light of vacuum wavelength 400 nm reaches the surface of the dense flint glass sphere (ii) The instant that red light of vacuum wavelength 700 nm reaches the surface of the dense flint glass sphere

Answer 1

option B (iv) (iii) (ii) (i)

This is because a denser medium provides more matter from which the light can scatter, so light will travel more slowly in a dense medium.Here dense flint glass has higher refractive index than that of quartz.The relationship between the frequency (the number of wave crests that pass by a certain point in a given amount of time) and wavelength for electromagnetic waves is defined by the formula, c = λ f, where c is the speed of light, λ the wavelength in meters, and f equals the frequency in cycles per second.So we know that velocity and frequency are directly proportional/So higher frequency travels faster .

So this order.
