Superposition and Interference
Superposition occurs when two or more waves pass through each other. When two or more waves superimpose, the amplitudes are added together. It creates constructive interference or destructive interference.
Light & Wave Simulation
Newton Ring
The Newton ring The interference of two reflections causes Newton rings. We can observe the Newton Rings when light is reflected from a plano-convex lens of a long focal length placed in contact with a plane … more
Diffraction Grating
The diffraction grating is a transparent plate with very narrow lines on the surface. Light (photons) like to go in the same phase. In the same phase, constructive interference occurs. If the phases are different, the … more
Why does a CD reflect rainbow colors?
Adjust the wavelength of light to choose the color of light you want. If you adjust the angle of reflection correctly, the phases of the light may coincide. That angle is the angle at which light … more
Polarization
Polarizers are made of long-chained molecules which absorb light with electric fields. When you shine a light on a polarizer, only a part of the light is passed. The polarizing plate materials absorb only the electric … more
Electromagnetic Waves around of Visible Rays
Electromagnetic radiation refers to the electromagnetic field waves radiating through space-time, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Types of Electromagnetic Wave Electromagnetic waves are classified … more
Thin Film Interference
Interference patterns seen in thin films If a thin oil film is floating on the water, you will see a beautiful pattern appear on the oil film. This is because the two waves interfere with each … more
Color Panel
Selecting the button to changes the background color. Use it when you need a specific color in various scientific experiments.
See the Light
Even if the object does not shine by itself, why can we see it? The eye is the organ that feels light. Even if the object does not shine by itself, why can we see it? … more
Why is the Sky Blue?
What is the size of the light? There is no exact concept of sizing the light, but it uses the wavelength of the light. Wavelength is the distance traveled by a wave before it vibrates once … more
Standing Waves in various situations
A standing wave occurs when incoming and reflected waves interfere with each other. It produces a wave pattern that appears to be stationary. Nodes are locations where particles of the medium appear to be at rest. … more
Rainbow Formation
A rainbow is a natural phenomenon where the dispersion of light is most visible. As you know, We can see a rainbow after it rains because the water droplets bend and disperse the light. For example, … more
