Answer 1

oops!!!!!!!!! Calculate the wavelength associated with cricket ball of mass of 150 g travelling with a velocity

of 25 ms-

​

Answer 2

According to the de-Broglie equation,

$wavelength \: = \frac{h}{mv}$

h = Planck's constant

h = Planck's constanth = 6.626 × 10^-34 Js

h = Planck's constanth = 6.626 × 10^-34 Jsm = 150 g

h = Planck's constanth = 6.626 × 10^-34 Jsm = 150 g= 150/1000

h = Planck's constanth = 6.626 × 10^-34 Jsm = 150 g= 150/1000 v = 25 m/s

h = Planck's constanth = 6.626 × 10^-34 Jsm = 150 g= 150/1000 v = 25 m/sPutting in equation, we get

$wavelength \: = \: \frac{6.626 \times 10 {}^{ - 34} Js}{( \frac{150}{1000} kg) \times 25ms {}^{ - 1} }$

$wavelength = 1.766 × 10 {}^{ - 34} m$
