Refraction of light - Huygens' Principle
To elucidate the rationale behind the bending of light as it transitions between different mediums, Huygens' principle is predominantly employed. The procedure, as demonstrated in this video (link: ...

Understanding Snells Law in seismic waves
This is a homework question, Ill say it upfront.
The Problem is given so:
Earthquake causes a wave that meets a boundary between two rock substances. Incoming wave speed is 25 m/s and angle is 9 ...

Path of sound in ocean where sound speed varies linearly with depth
In an ocean, described with $x-y$ Cartesian coordinates where $y=0$ on the sea bed, the sound speed varies linearly with $y$:
$$v(y)=c+by$$
A textbook says that, if sound wave is emitted on the sea ...

Confusion over Snell's law [duplicate]
Does the angle of refraction always have $n_2$ as its refractive index? As far as I know, $$\frac{\sin\theta_i}{\sin\theta_r} = \frac{n_2}{n_1}.$$
So I got this question here:
Calculate the ...

The impact of refraction on a double slit interference pattern
Source: isaacphysics.org
This set up, without the glass, would produce a standard interference pattern, with a bright central maximum followed on both sides by progressively dimmer maxima.
Placing a ...

Two layers of glass reflection related to wave interference [closed]
A highly reflective mirror can be made for a particular wavelength at normal incidence by using two thin layers of transparent materials of indices of refraction $n1$ and $n2 (1 < n1<n2 ) $on ...
