What will be the wavelength of a ball of mass 0.1 kg moving with a velocity of 10 m s–1 ?
The mass of an electron is 9.1×10–31 kg. If its K.E. is 3.0×10–25 J, calculate its wavelength.
Calculate the mass of a photon with wavelength 3.6 Å.
A microscope using suitable photons is employed to locate an electron in an atom within a distance of 0.1 Å. What is the uncertainty involved in the measurement of its velocity?
A golf ball has a mass of 40g, and a speed of 45 m/s. If the speed can be measured within accuracy of 2%, calculate the uncertainty in the position.
Calculate the wavelength of an electron moving with a velocity of 2.05 × 107 m s–1.
