 A photon has energy of 2.6 eV. What is its wavelength?

 If uncertainty in the position of an electron is zero, the uncertainity in its momentum would be

Uncertainty in the position of an electron (mass 9.1 x 10^-31 kg) moving with a velocity of 300 ms^-1, accurate upto 0.001% will be:

 What experimental result did Albert Einstein cite as evidence that light has particle-like properties?

The de Broglie wavelength of a particle is given by.

The de – Broglie wavelength of an electron is 600 nm. The velocity of the electron having the mass 9.1 X 10^-31 Kg is

In the relationship ∆x. ∆p =   , ∆p is:

The uncertainty principle states that

 Whch of the following will have the maximum value of ∆v . ∆x

The de Broglie wavelength of an electron is 8.7 x 10^-11 m. The mass of an electron is 9.1 x 10^-31 kg. The velocity of this electron is:
