Quantum Mechanics

Schrodingers wave equation describes the

• Motion of light

• Procedure for splitting of an atom

• Behaviour of matter waves

• Complement of wave function

Frequency below which no electrons are emitted from metal surface is

• Minimum Frequency

• Maximum frequency

• Threshold frequency

• Angular Frequency

Wavelength of matter waves is indepenent of

• Charge

• Velocity

• Momentum

Debroglie wavelength wavelength of a particle is

• Inversely proportional to momentum

• Directly proportional to velocity

• Inversely proportional to mass

• Directly proportional to energy

Choose the correct statement:

• Only Charged particles in motion are accompanied by matter waves

• No paticle wheteher at rest or in motion, is ever accompanied by matter waves

• Only sub atomic aprticles in motion are acompanied by matter waves

• Any particle in motion, whether charged or uncharged, is accompanied by matter waves

Velocity of light is ----------------- velocity of matter wave

• greater than

• same as

• smaller than

• Independent
