what is Hertz? How we convert kilohertz to Hertz (kHz to Hz) with Examples

Hertz Hertz is the SI (International System of Units)  of unit frequency. It is the derived unit  that express in Hz. Hertz is defined as cycles per one second. It is commonly expressed in multiples: kilohertz (103 Hz, kHz), megahertz (106 Hz, MHz), gigahertz (109 Hz, GHz), terahertz (1012 Hz, THz), petahertz (1015 Hz, PHz). This unit are sometimes also used for … Read more

Solar Energy | Definitions and Applications | Description, Uses, & Facts

Solar energy It is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar architecture, solar heating, photovoltaic, solar thermal energy,  molten salt power plants and artificial photosynthesis. It is a very important source of renewable energy and its technologies are broadly characterized as either active solar or passive solar depending on how they capture and provide … Read more

Light Energy – Creation, Properties, Uses & Light energy examples

Light energy is a type of kinetic energy because it deals with the speed of photons. Light energy is defined as a form of electromagnetic radiation emitted by the hot object like bulb, sun or fire e.t.c. Light Energy The light energy contains photons which are energy packets. The photons are emitted from atom both … Read more

Wind energy – How Wind Energy formed & major types of wind power

Wind energy is a form of solar energy. In this topic we describe the process by which the wind is used to generate electricity. Wind turbines convert the kinetic energy of the wind into mechanical power that rotate the fan. A generator is used to convert mechanical power into electrical power. Mechanical energy can also be utilized directly … Read more

Sound Energy – sound energy definition, examples & facts

Sound energy is a form of energy that can be heard by the human ear. Sound is a mechanical wave so it needs medium for their propagation. It consists physically in oscillatory elastic compression and in the oscillatory displacement of a fluid. So the medium acts as storage for both kinetic and potential energy. Sound Energy Consequently, the sound energy is defined as the sum of the potential … Read more

Define Hydroelectricity & Hydropower | Types, advantages & disadvantiges

Hydroelectricity is the form of electricity made by generators that are pushed by the movement of water. It is usually made with dams that make to block a river to collect the water that is pumped there. When the water is released, the very high pressure behind the dam forces the water downpipes that lead to a turbine. This causes … Read more

Definition & Describe all Types of Energy [20 types of energy]

What is energy in science Energy is the capacity of doing work. It is the quantitative properties that transfer from one object to another object. Its unit is joule. Energy is a conserved quantity. This means that the total energy of the system remains constant but it converts from one form to another form. For … Read more

ENERGY definition | Law of Conservation of Energy – Types of Energy Transfer

It is the quantitative property that must be transferred from one object to another object in order to perform work or to transfer heat. The SI unit of energy is joules. It is derived unit. One joule is equal to the force applying of one Newton through a distance of one meter. Define law of conservation of energy?   This law states that the … Read more
