Question

Calculate the wavelength of a ball of mass 0.1 kg movng with velocity of 10 m/s

Answer 1

Hey dear !!

Question => Calculate the wavelength of a ball of mass 0.1 kg moving with velocity 10 m/s ?

Solution =>

Mass of the ball = 0.1 kg

Velocity of ball = 10 m/s

A

According to De Broglie equation ;

Wavelength = h/mv

Whereas '' height = 6.626 × 10^-34 m

=> ( 6.626 × 10^-34 ) / ( 0.1 × 10 )

=> ( 6.626 × 10^-34 ) / 1

=> 6.626 × 10^-34 m

Hence " wavelength is 6.626 × 10^-34 m

Thanks!!
