Frequency is an important property of all waves and the amount of energy contained in each wave is related in proportion to its frequency. The higher the frequency of the wave, the more energy a wave has and vice versa. In our case of visible light, the highest frequency color, which is violet, which means it will have the highest energy. Similarly, red has the lowest frequency, so it will have the least energy.Mathematically,\[c=\nu \lambda \]where, c = speed of light in a vacuum.\[\nu \] = frequency \[\lambda \] = wavelengthNow on rearranging,\[\nu =\dfrac{c}{\lambda }\]We can see that wavelength is indirectly proportional frequency i.e. as wavelength decreases, frequency increases. Energy (E) can be written as,\[E=\hbar \nu \]Where,\[\hbar \] = Planck's constant.We can conclude that as the wavelength decreases, frequency increases which leads to increase in energy.Looking at our option, wavelength of each spectrum is:Violet = 380-450 nmGreen = 495-570 nmYellow = 570-590 nmOrange = 590-620 nmRed = 620-750 nmTherefore, the correct option is (a).Note: As we can see red light has the highest wavelength, it scatters the least, which is why it can travel longer distances through rain, fog or dust and reach our eyes effectively.Recently Updated PagesMaster Class 11 English: Engaging Questions & Answers for SuccessMaster Class 11 Maths: Engaging Questions & Answers for SuccessMaster Class 11 Biology: Engaging Questions & Answers for SuccessMaster Class 11 Social Science: Engaging Questions & Answers for SuccessMaster Class 11 Physics: Engaging Questions & Answers for SuccessMaster Class 11 Accountancy: Engaging Questions & Answers for SuccessMaster Class 11 English: Engaging Questions & Answers for SuccessMaster Class 11 Maths: Engaging Questions & Answers for SuccessMaster Class 11 Biology: Engaging Questions & Answers for SuccessMaster Class 11 Social Science: Engaging Questions & Answers for SuccessMaster Class 11 Physics: Engaging Questions & Answers for SuccessMaster Class 11 Accountancy: Engaging Questions & Answers for Success
