The de Broglie wavelength of a tennis ball of mass 60 g moving with a velocity of 10 meters per second is approximately

Accepted Answer

As per de-Broglie wavelength of a particle is

Wavelength (

\lambda

) =

{h \over {mv}}

Where h is plank's constant, m is mass of the particle and v is the velocity of the particle

\therefore \lambda

=

{{6.63 \times {{10}^{ - 34}}} \over {0.06 \times 10}}

=

{{6.63 \times {{10}^{ - 34}} \times 10} \over {0.6 \times 10}}

=

{{6.63 \times {{10}^{ - 33}}} \over 6}

\cong 10{}^{ - 33}
