A light source emitting radiation at 7.00 x 10¹4 Hz is incapable of ejecting photoelectrons from a certain metal. In an attempt to use this source to eject photoelectrons from the metal, the source is given a velocity toward the metal. b) When the speed of the light source is equal to 0.280c, photoelectrons just begin to be ejected from the metal.
