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
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
Why we can’t see atoms under an optical microscope? The process by which we see objects is based on light. Therefore, the resolution of object recognition depends on the light. Just as a tool must be precise to open a … more
