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 is reflected by interference. … more
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 field component of light … more
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 based on the length … more
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 other. One wave is … more
Selecting the button to changes the background color. Use it when you need a specific color in various scientific experiments.
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? Most objects can reflect … more
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 and returns to its … more
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. And, antinodes are locations … more
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, if we spray water … more
Color and Eye Recognition Visible light has various colors. Light has a different color depending on the wavelength (or frequency). So, how do people perceive color? Cone cells in the eye’s retina recognize color. There are three kinds of cone … more
Why is the incident angle and the reflection angle the same? ‘Law of reflection’ has the word ‘law’ attached. ‘Law’ refers to a situation in which a natural phenomenon happens repeatedly and without exceptions. In other words, ‘law’ only tells … more
The law of reflection Consider a light-ray incident on a plane mirror, the angle of reflection is equal to the incidence angle. This is the law of reflection. When looking at the end of the head and feet with a … more
