Can anyone explain the relationship between the refractive index, the speed, wavelength and angle of a wave?
Can anyone explain the relationship between the refractive index, the speed, wavelength and angle of a wave?
in my book is states that $$n = \frac{v_1}{v_2} = \frac{\sin θ_1}{\sin θ_2} = \frac{λ_1}{...

Does refraction depend on the colour of light?
Consider passing red and yellow lights separately through the same interfaces and with the same angles of incidence.
Light of which colour will be refracted more?
This question was given to me. All I ...

Why refractive index of same material is different for different monochromatic lights?
Yeah I know that refractive index is different for different monohromatic lights due to the change in velocity of light. And as frequency doesn't changes and only wavelength changes while travelling ...

Why is the two-term form for the Cauchy equation sufficient?
The general Cauchy equation for the relationship between refractive index and wavelength is given by,
$$n = A + \frac{B}{\lambda^{2}}+\frac{C}{\lambda^{4}}+...,$$
but this is often approximated to
$$...

Why does violet light bend the most? [duplicate]
When white light passes through a prism, refraction occurs and it splits into its seven constituent colours. If the spectrum is obtained on a screen violet light appears much more bent than red light.

Refractive index and wavelength relation [duplicate]
In general, the refractive index of a certain medium tends to decrease with increasing wavelength.
But are there any materials in which the opposite phenomenon occurs? That is, in which the ...
