Q1

An electromagnetic wave of wavelength \( \lambda \) is incident on a photosensitive surface of negligible work function. If '\(m\)' mass is of photoelectrons emitted from this surface has de-Broglie wavelength \( \lambda_{d} \) then
[NEET 2021]

a

\(\lambda=\left(\frac{2 m }{hc}\right) \lambda_d{ }^2\)

b

\(\lambda_d=\left(\frac{2 m c}{h}\right) \lambda^2\)

c

\(\lambda=\left(\frac{2 m c}{h}\right) \lambda_d{ }^2\)

d

\(\lambda=\left(\frac{2h}{mc}\right) \lambda_d{ }^2\)
