Light refers to electromagnetic radiation that can be detected by the human eye. The entire electromagnetic spectrum is extremely broad and it ranges from low energy radio waves of the wavelength range from 10^-3 to 10^-1 meters to high energy gamma rays with wavelengths that range from 10 ^-11 to ...

Phases of Moon :  * Full Moon * Waxing Gibbous * First Quarter * Waxing Crescent * New Moon  * Wanning Crescent * Third Quarter * Wanning Gibbous. These are the different phases of moon. We cannot see the other side of moon.  Tidal forces from the Earth slowed down ... Read More

Given below are some properties of the materials that can be studied to group materials together. • Appearance: The look, feel, and texture in addition to lustre, colour and quality defines the property of the appearance of the material. • Soluble/Insoluble: The nature of the material to completely dissolve in ...

Separate salt from saltwater: Evaporation :  * The most common way to separate salt from saltwater is evaporation. * Usually salt has a much higher boiling point than water. So, when a salt solution is heated, water gets evaporated, leaving behind salt ... Read More

Longitude is nothing but the angular distance of a place east or west with respect to the meridian at Greenwich, England. It is nothing but to say where a place is located on the planet earth. For example, Delhi's longitude is 78.10 degrees east.

Ohm's law states that the voltage across a resistor is directly proportional to the current flowing through it. Ohm's law is named for German physicist Georg Ohm. In simple terms, Ohm's law gives the relationship between current, voltage, and resistance. V = irwhere, V = voltage across resistori = currentr = resistence

The design of the bathroom is in such that the wastage water would go to a corner of a room, where a hole is provided. All the other three corners are constructed at a little bit more height than the corner where the hole is provided. The height level was ... Read More

A filament is a thin wire with two bigger wires holding it up. Whenever electricity flows through the filament, it glows. Generally, filaments have high resistance, therefore, when electricity passes through them, they heat up and start glowing, converting electrical energy to heat energy. Filaments in incandescent bulbs are ... Read More

Force: * Force is essentially a push, or a pull action, that can lead to certain outcomes. * It can deform a body or can change the state of motion of a body. * Mathematically, it is the product of mass and acceleration. * Some examples of ... Read More
