Physics Questions

The photoelectric effect pointed to the particle properties of light, which had been considered to be a wave phenomenon. Particles like electron and protons have both particle like and wave like behavior. Thus, according to de Broglie, all the material particles in motion possess wave characteristics. Although the dual nature of matter is applicable to all material objects but it is significant for microscopic bodies only.

It forms slow crystallization of magma below Earth's surface.Granite is a hard light-colored igneous rock and it is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles and other minerals it is mainly used for building and monuments

An ideal gas cannot be liquified because forces between the molecules are negligible.

The odometer or the odograph is an instrument used to indicate the distance travelled by the vehicle.

If it loses an electron it becomes a positive ion

The frequency of a sound wave is determined by the amplitude of the wave. As amplitude of the wave is high the frequency of the wave will also be high.
