Light of wavelength \( (\lambda) \) strikes a metal surface with intensity \( X \) and the metal emits \( Y \) electrons per second of maximum kinetic energy \( Z \). What will happen to \( Y \) and \( Z \) if \( X \) is halved?
(a) \( Y \) will be halved and \( Z \) will be doubled.
(b) \( Y \) will be doubled and \( Z \) will be halved.
(c) \( Y \) will be halved and \( Z \) will remain the same.
(d) \( Y \) will remain the same and \( Z \) will be halved.
