Optical Experiments

Optical Experiment Simulator

It is an optical experiment simulator consisting of a slit laser, lenses, and mirrors of various shapes. You can experiment by dragging the tool you want. Slit lasers are rotatable. Try dragging the red icon behind … more

Principle of least time (Fermat's principle)

Principle of least time (Fermat’s principle)

Why does a slightly curved path take less time than a straight path? Ants can move faster on flat stones than on rugged grass. Therefore, travel time is the shortest on slightly curved paths. This principle … more

Light Refraction

Light Refraction

You can drag the path of light. Refraction is the bending of a wave caused by a change in its speed as it moves from one medium to another. This occurs because of the slow speed … more

Why do you always have crystal ball covered?

Why do we always have crystal ball covered?

Why do we always have crystal ball covered? While surfing the web, I came across a fascinating article on Twitter. It sounds like a fun topic, so we decided to simulate the refraction of all light … more

Rainbow by Raindrops

Rainbow by Raindrops

A rainbow is a natural phenomenon where the dispersion of light is most visible. As you know, We can see a rainbow after rain because the water droplets bend and disperse the light. For example, if … more

Refraction on water

Refraction on water

Refraction is the bending of a wave caused by a change in its speed as it moves from one medium to another. This occurs because of the slow speed of light in dense materials. Examples of … more

Prism

Prism

The refractive index of the prism glass was assumed to be 1.51 for red light (≒700 nm) and 1.53 for blue light (≒400 nm). The speed of light is about 300,000km/s. Light travels fastest in a … more
