A particle moves in a closed orbit around the origin, due to a force which is directed towards the origin. The de-broglie wavelength of the particles varies cyclically between two values `lambda_(1), lambda_(2) with lambda_(1)gtlambda_(2)`. Which of the following statements are true?

A

the particle could be moving in a circular orbit with origin as centre

B

The particle could be moving in an elliptic orbit with origin as its focus

C

When the de-broglie wavelength is `lamda_(1)` the particle is nearer the origin than when its value is `lamda_(2)`

D

When the de-broglie wavelength is `lamda_(2)`, the particle is nearer the origini than when its value is `lamda_(1)`.
