Answer:
True
Explanation:
Matter can be in the form of a particle or a wave. This is known as the dual nature of matter. This concept was proposed by Louis de Broglie and was named after him. This phenomenon has been observed for all the elementary particles.
The de Broglie wavelength is given by

Where
h = Planck's constant
p = Particles momentum
m = Mass of particle
v = Velocity of particle
1. Delta, is formed by constructive erosion.
Answer:
