NEET Physics de Broglie Wavelength MCQ Question
Calculate the de Broglie wavelength of a proton moving at a speed of 2.0 × 10^6 m/s. (Mass of proton = 1.67 × 10^-27 kg, Planck's constant h = 6.63 × 10^-34 J s)
1.99 × 10^-14 m
3.31 × 10^-14 m
2.76 × 10^-14 m
4.15 × 10^-14 m
Correct Answer
Detailed Explanation
Using the formula λ = h/p, where p = mv, we calculate the momentum and substitute to find the de Broglie wavelength. This is similar to the provided example in the NCERT context.
