Do Normal Incidence contradicts the definition of refraction?
Professor told our class that if someone wants to define refraction in words, it can be done as the following, The deviation of light from its path when it passes from one medium to another is called ...

Shouldn't a part of the ray have to travel $\frac{\lambda_2}{2}$ extra path in the medium $n_2$?
Basically, my teacher had given the class a question regarding thin film interference that, there is a medium with refractive index $n_1$ below that there is another medium with thickness $t$ with ...

If a beam of light follows the path $y(x)=y_0\sin(x/y_0)$, what is the index of refraction?
An exam question that showed up while I was studying:
A plane wave refracts and follows a ray given by the equation $y=y_0\sin(x/y_0)$ where $y_0$ is a constant. Find the refractive index $n(y)$ ...

Laser travelling through a radially graded index of refraction
A laser beam propagates through a region whose refractive index varies as $\mu=\mu_0(\frac{r}{r_0})$. At a distance of R the beam makes an angle of 30° with the normal.
Find the minimum seperation ...

How can the image be any size orher than the object?
Am image is just the set of images of all the points on the thing. The complete image has to be the same size as the object if there is exactly one image for each point on the object forming it. So an ...

Why does a qualitative analysis of this question about refraction differ from the answer found through the application of the equation?
Suppose that an object O is in glass ($ \mu $ = 1.5), 6.5 cm from a spherical glass-air interface (from P in Figure 1) where glass is on the concave side and air is on the convex side. In the diagram ...
