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

Adjusting Camera Exposure and Focus

Adjusting Camera Exposure and Focus

Camera In optics, an image is recreated by collecting some of the light emitted by an object. Devices that recognize images include eyes and cameras. The light entering the camera passes through the aperture and lens, … 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

Evolution of the eye

Evolution of the eye

Flagellate Hundreds of millions of years ago, light-sensing organelles arose inside the monad. Creatures with ‘photoreceptors’ are able to distinguish day and night and can also avoid harmful ultraviolet light. Flatworm And these photoreceptors have evolved … more

Correction of Near-sightedness & Far-sightedness

Correction of Near-sightedness & Far-sightedness

Focusing The light started from the object must have arrived exactly at one point on the retina to see things in detail. On the other hand, if the light from one point of the object is … 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

Convex Lens & Concave Lens Simulation

Convex Lens & Concave Lens

Real image and virtual image Looking at an object, we feel there is an object in it. By the way, if you feel that there is something, we say there is an ‘image,’ even if there … 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

Camera

Camera

Focus adjustment of the camera The eye focuses by adjusting the thickness of the lens. On the other hand, the camera focuses by adjusting the position of the lens. Focusing The light started from the object … 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
