Textbook Problem

Traffic signals are often now made of LEDs (light-emitting diodes). Amber and green ones are pictured here.

  1. (a) The light from an amber signal has a wave-length of 595 nm, and that from a green signal has a wavelength of 500 nm. Which has the higher frequency?
  2. (b) Calculate the frequency of amber light.

(a)

Interpretation Introduction

Interpretation: The light having higher frequency has to be determined among amber and green light.

Concept introduction:

  • Electromagnetic radiations are a type of energy surrounding us. They are of different types like radio waves, IR, UV, X-ray etc.
  • The visible light lies in the region between 400nm and 700nm.
  • The frequency of the light is inversely proportional to its wavelength.

  ν=cλwhere, c=speedoflightν=frequencyλ=wavelength

Explanation

The wavelength of amber light is 595nm and the wavelength of green light is 500nm. According to the relation between wavelength and frequency,ν </

(b)

Interpretation Introduction

Interpretation: The frequency of amber light has to be calculated.

Concept introduction:

The frequency of the light is inversely proportional to its wavelength.
