The de broglie wave is produced only by sub atomic particle and photon. o true o false

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

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
