λr > λy > λg . Here threshold wavelength < λy

Q. When yellow light is incident on a surface, no electrons are emitted while green light can emit. If red light is incident on the surface, then

No electrons are emitted

Photons are emitted

Electrons of higher energy are emitted

Electrons of lower energy are emitted

$λ_{r} > λ_{y} > λ_{g} .$ Here threshold wavelength $< λ_{y}$
