Aparticle has a de broglie wavelength of 2.1 × 10-10m. then its kinetic energy increases by a factor of 3. what is the particle's new de broglie wavelength, assuming that relativistic effects can be ignored?

Explanation:

given,

de broglie wavelength of the particle = 2.1 × 10⁻¹⁰m

Kinetic energy increase factor = 3

de broglie  wavelength of new particle = ?

we know,

Kinetic energy

...........(1)

Kinetic energy of other particle

............(2)

dividing equation (1)/(2)

unable to answer the rest since your question is incomplete

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
