Dual Nature of ...

In case of electrons and photons having the same wavelength. What is same for them ?

Which metal(s) can be used to produce electrons by the photoelectric effect from given source of light ?

The work function of aluminium is 4.2 eV. If two photons, each of energy 3.5 eV strike an electrons of aluminium, then emission of electrons

Each question contains statement 1 and statement 2. Choose the correct answer (only one option is  correct) from the following options.

If 5% of the energy supplied to a bulb is radiated as visible light, the number of visible quanta emitted per second by a 100W bullb, assuming the wavelength of visible light to be $$5.6 \times 10^{-5}cm$$, is

A material particle with a rest mass $$'m_0\ '$$ is moving with speed of light 'c'. The de-Broglie wavelength associated is given by

A monochromatic source of light operating at 200 W emits $$4 \times 10^{20}$$ photons per second. Find the wavelength of light.

Calculate the de Broglie wavelength for a beam of electron whose energy is 100 eV:

If velocity of a particle A is 50% of velocity of particle B and mass of B is 25% of mass of A then de-Broglie wavelength of B if wavelength of A is $$2\mathring A$$
