Find the ratio of de-Broglie wavelengths...

Find the ratio of de-Broglie wavelengths associated with two electron beams accelerated through 25 V and 36 V respectively.

Text Solution

Verified by Experts

de-Broglie wavelength associate with potential difference `lambda prop (1)/(sqrt(V))`
`(lambda_(1))/(lambda_(2)) = sqrt((V_(2))/(V_(1))) = sqrt((36)/(25)) = (6)/(5)" "rArr lambda_(1) : lambda_(2) = 6 : 5`
