Students are introduced to the term wavelength in optics at school level. In this paper, we present an inexpensive and simple method to measure the wavelength of the light of a light emitting diode using a light depending resistor. This experimental set-up is developed at Science Laboratory, Nehru Planetarium (Mumbai), India. It is useful as an experimental tool to teach the concepts of light in a simpler way.
