Question

calculate the wavelength in m/s associated with a 10g bullet moving at a velocity of 500m/s​

Answer 1

Explanation:

mass of bullet

=10g

= 10/100 = 0.01kg

and velocity = 500m/s

Now ,

we know that

$lembda = \frac{h}{mv}$

$lembda = \frac{6.626 \times 10 {}^{ - 34} }{0.01 \times 500}$

$lembda = \frac{6.626 \times 10 {}^{ - 34} }{5}$

$lembda = 1.32 \times {10}^{ - 34}$

hope it helped!

Answer 2

Mass = 0.01kg

lemda = n/mu

wavelength.

=( 6.626×10^-34 ) / 0.01×500

(6.626 × 10^-34)/5
