Acertain rifle bullet has a mass of 5.97 g. calculate the de broglie wavelength of the bullet traveling at 1025 miles per hour.

- wavelength of the bullet is .

Solution:- de-Broglie equation is:

where, is the de-Broglie wavelength, h is planck's constant, m is the mass in kg and v is the velocity in meter per second.

The given mass of the bullet is 5.97 g. Let's convert it to kg:

since, 1 kg = 1000 g

= 0.00597 kg

velocity is given as 1025 miles per hour. Let's convert it to meter per second as:

=

Value of planck's constant is .

Let's plug in the values in the equation and solve it for the wavelength.

note:( )

So, the wavelength of the bullet is .
