When a ray of light is incident at normal incidence, (at right angles), to the surface between two optical materials, the ray travels in a straight line. When the ray is incident at any other ...

In this required practical activity, it is important to: make, measure and record the angles of incidence accurately using a protractor; observe and use a protractor to measure angles of refraction.

Daylight enhances well-being and has many advantages over artificial lighting. Sensible daylight management can therefore increase the ability to perform and concentrate. As less artificial light is ...

The optical distortion was evaluated by recording the image height versus the angle of incidence (AOI). The compound metalens demonstrated a linear dependence of image height on AOI, validating ...
