Question

which of the following is not a variable in the de Broglie equation?
a) wavelength
b) velocity
c) Planck's constant
d) Location​

Answer 1

Answer:

c) Planks constant

Explanation:

Because its value is fixed as 6.626×10^-34.Location is not included in the formula.

Answer 2

Planck's constant is not a variable in the De- Broglie equation.

Explanation:

• Matter waves are those waves that are associated with particles in motion.
• De Broglie's equation -  λ=h/mv,
• where λ is the de Broglie wavelength,
• λ lambda represents the wavelength, h is Planck's constant,
• m is the mass and v is the velocity of the particles.
• de Broglie equation states the dual nature it states that a matter can act as waves much like light and radiation, which also behave as waves and particles.
• These equations also describes the wave nature of the electron.
