Does TV use microwaves or radio waves? Microwaves are used because they pass through the atmosphere and through the ionosphere. The signals may be for television programmes, telephone conversations, or monitoring the Earth (for example, weather forecasting). Should I turn off wifi at night?

Can we convert mass to energy?
Can we convert mass to energy? First discovered by Einstein more than 100 years ago, it teaches us a number of important things. We can transform mass into pure energy, such as through nuclear fission, nuclear fusion, or matter-antimatter annihilation. Can mass be converted into energy or can mass be destroyed? The total mass of […]
How do you classify hydrogen?
How do you classify hydrogen? Hydrogen is most often classified as a nonmetal because it has many of the properties of nonmetals. For example, it is a gas at room temperature. However, hydrogen shares properties with the alkali metals in group 1. In liquid form, hydrogen conducts electricity just like a metal does. Can we […]

What are two recently discovered state of matter?
What are two recently discovered state of matter? The two newly discovered states of matter are Plasma and Bose-Einstein Condensate. Does liquid glass exist? Glass, however, is actually neither a liquid—supercooled or otherwise—nor a solid. It is an amorphous solid—a state somewhere between those two states of matter. And yet glass’s liquidlike properties are not […]

What happens when an insulator is placed in an electric field?
What happens when an insulator is placed in an electric field? When an insulator, also called the dielectric, is placed in an electric field, it gets polarised. The polarised dielectric reduces the effective electric field. Can an insulator have an electric field? We define a conductor as a material in which charges are free to […]
