Question

12.Calculate the wavelength of an object moving with a velocity of 5 x105 m s-1

.(h = 6.6x10-34 J s; mass of the object = 4 x10-22 kg)

Answer 1

Wavelength,
`\lambda=3.3* 10^(-18)\ m`

Step-by-step explanation:

We have,

Velocity of the object,
`v=5* 10^5\ m/s`

Mass of the object,
`m=4* 10^(-22)\ kg`

It is required to find the wavelength of the object. The relation between wavelength and velocity of the object is given by :

`\lambda=(h)/(mv)`

h is Planck's constant

`\lambda=(6.6* 10^(-34))/(4* 10^(-22)* 5* 10^5)\\\\\lambda=3.3* 10^(-18)\ m`

So, the wavelength of the object is
`3.3* 10^(-18)\ m`.
