Quantum Mechanics_Activity I

Concept of "Quanta" was coined by

• Albert Einstein

• Max Planck

• Louis de Broglie

• Werner Heisenberg

Waves that are associated with the particle

• Acoustic waves

• Electromagnetic waves

• Matter waves

Concept of matter waves was proposed by

• Max Planck

• Albert Einstein

• Lenard

• Louis de Broglie

• Proton with uniform velocity

• Electron with uniform velocity

• Photon

• accelerated particle

For the massive size particle, the wavelength will be

• shorter

• longer

• in visible region

Particles, at rest exhibits the wave nature

• Yes

• No

Heisenberg Uncertainty principle is

In Quantum mechanics, which of the following concept plays a vital role

• Position

• Velocity

• Momentum

• Energy

In Quantum mechanics, the uncertainty is due to

• inefficiency of measuring instruments

• insufficient measuring techniques

• wave nature of the particle

• All the above

The path of the quantum particle can be traced out with precision

• True

• False
