Question

Light from three different lasers (A, B, and C), each with a different wavelength, was shined onto the same metal surface. Laser A produced no photoelectrons. Lasers C and B both produced photoelectrons, but the photoelectrons produced by laser C had a greater velocity than those produced by laser B. Arrange the lasers in order of increasing wavelength.
C shortest
B longer
A none
cab
iuot
BAC
A: shortest wavelength
C: nothing
B : Longest wavelength

A<C<B
what was the right answer
The right answer is B<A<C
