It is called the trough.
Light is both a wave and a particle depending on circumstances; this is referred to as the wave-particle duality of light.
wave
a partical wave is the name of normal wave
a particle traveling in wave form.
The disturbance traveled from one end to the other end in a medium without the acutal moment of particle is called wave motion.
wave theory of light
Alpha is a particle not a wave. Alpha particle are positively charged helium nuclei and have a +2 charge and 4u mass.
Einstein. He stated that light acts as both a particle and a wave.
The wave-particle duality applies to any object (or wave); not just to light.This is usually understood in the sense that the wave represents the probability of finding the particle in different places.
A wave is a a moving oscillation that transfers energy through a medium. A particle is an object.
Both. E = mc2(squared) wave is an energy form while m is mass (particle) einstein proved that light acts as wave and particle at the same time.
In a transverse wave the particle displacement is perpendicular to the direction of wave propagation (at right angles). In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.
