Explain the wave-particle duality of light. (b) A particle of wavelength 4.2x 10\(^{-11}\)m travels (a) With a momentum of 1.6 x 10\(^{-23}\) kg m/s,

Determine the value of the Planck's constant, h.

The answer to the a part is actually supposed to be:
Light can act as both a particle (by way of photon) and also as a wave (but not simultaneously)

E=(h×c(speed of light))÷ wavelength.
Make h subject formula
4.2×10^-11× 1.6×10^-23 ÷ 3.0×10^8
= 2.24 ×10^-42
