What are the disadvantages of using a pinhole camera?
What are the disadvantages of using a pinhole camera? The image formed does not give any details. Usually, it is faint. Image is obtained on the screen and no permanent record of the image can be obtained. Pinhole camera cannot be used for studying moving objects.

What is heat loss by radiation?
What is heat loss by radiation? Radiation is a form of heat loss through infrared rays. This involves the transfer of heat from one object to another, with no physical contact involved. For example, the sun transfers heat to the earth through radiation. The last process of heat loss is evaporation. How can a patient […]
What are the major components of a projectile motion?
What are the major components of a projectile motion? There are the two components of the projectile’s motion – horizontal and vertical motion. And since perpendicular components of motion are independent of each other, these two components of motion can (and must) be discussed separately. What is the vertical component of the velocity just before […]
What is an electromagnet give its characteristics?
What is an electromagnet give its characteristics? An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity. […]
