What is the function of semiconductor? A semiconductor can help controlled flow of electricity. The basic function of such a device is to switch ON and OFF the flow of electricity as and when required. A semiconductor device can perform the function of a vacuum tube with hundreds of times its volume. What is N […]

Which has more energy infrared or ultraviolet?
Which has more energy infrared or ultraviolet? Ultraviolet radiation carries more energy and infrared radiation less energy than visible light. Does ultraviolet carry energy? Simply put, ultraviolet radiation (also known as UV radiation or ultraviolet rays) is a form of energy traveling through space. Some of the most frequently recognized types of energy are heat […]
Is it bad to look at IR light?
Is it bad to look at IR light? All infrared, visible or ultraviolet electromagnetic radiation can cause injury to the eye in sufficient concentrations, but this is very rare. Infrared lamps and incandescent bulbs are not powerful enough to cause such harm. But it’s best if you don’t stare directly at them for too long. […]
How do emotions affect our perception?
How do emotions affect our perception? Emotional arousal guides attention so that people’s attention tends to be drawn to objects that are arousing.

What is the basic principle of air wedge experiment?
What is the basic principle of air wedge experiment? The phase difference between the two rays is used to get interference fringes. It’s alternative light and dark fringes. The path difference between the rays has to be equal. What is meant by air wedge? Air Wedge. An air wedge is a simple interferometer used to […]
What electromagnetic waves can be used for communication?
What electromagnetic waves can be used for communication? Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction. These properties make them ideal for communications. Which wave […]
What is center of projection?
What is center of projection? The center of projection is the origin or source of the stream of projecting rays. Depending on the distance between the center of projection and the image plane, the distinction should be made between central (conical) projections and parallel (cylindrical) projections. What is foreshortening factor? 3) The ratio of projected […]
Why is a normal eye not able to see clearly the objects placed closer than 25cm?
Why is a normal eye not able to see clearly the objects placed closer than 25cm? Explanation. A normal eye cannot see clearly the objects that are placed closer than 25cm because the power of accommodation of the eye is 25cm which is exhausted. When the maximum accommodation of the eye is reached, the ciliary […]
