Questions tagged [reflection]
This tag is for questions relating to reflection, the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. A familiar example of reflection comes from water waves; as the waves travel they reflect off objects that are floating in the water, and also reflect off the walls of the container holding the water.

What causes an object to be more reflective than refractive?
This is a question that a high school student asked me and I couldn't give him a satisfactory answer. He started by saying that
An object appears red because the energy corresponding to a "red&...

Influence of absorption, reflectance and light source on interference in thin films
I am not a physicist, but reading up on interference in thin films.
I understood how the relation of two interfering light waves intensities $I_1$ and $I_2$ of a thin film (the first reflected at the ...

Why didn't I reach $\frac{1}{p}+\frac{1}{q}=\frac{1}{f}$?
In optics for convex and concave mirrors there is the following formula: $$\frac{1}{p}+\frac{1}{q}=\frac{1}{f}$$ where $p$ is the distance between the object and the mirror, $q$ is the distance ...
