Question The de-Broglie wavelength of a bus moving with speed \( v \) is \( \lambda \). Some passengers left the bus at a stoppage. Now when the bus moves with twice its initial speed. Now kinetic energy is found to be twice its initial value. What will be the de-Broglie wavelength, now:
(A)  \( \lambda \)
(B) \( 2 \lambda \)
(C) \( \lambda / 2 \)
(D) \( \lambda / 4 \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
