Question

The de broglie wavelength associated with a ball of mass 1 kg having kinetic energy 0.5J is​

Answer 1

Answer:

h = 6.626 x 10^-34 m^2 kg/s

Explanation:

Using K.E formula

0.5 = 1/2 x 1 x v^2

v^2 = 1

v = 1

.....

Wavelength = h/mv

                     = h / 1x1

                     = h  = 6.626 x 10^-34 m^2 kg/s
