The dual nature of light is exhibited by:
Correct answer: A. diffraction and photoelectric effect
- A. diffraction and photoelectric effect
- B. diffraction and reflection
- C. diffraction and interference
- D. photoelectric effect
Explanation
Diffraction exhibits wave nature of light and photoelectric effect exhibits quantum nature of light. Therefore, diffraction and photoelectric effect exhibit the dual nature of light.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.

An image of the sun is formed by a lens of focal length 30 cm on the metal surface of a photoelectric cell and it produces a current I. The lens forming the image is then replaced by another lens of the same diameter but of focal length 15 cm. The photoelectric current in this case will be: (In both cases the plate is kept at the focal plane and normal to the axis lens)
Quantum nature of light is explained by which of the following phenomenon:
A modern 200-watt sodium street lamp emits yellow light of wavelength 0.6 µm. Assuming it to be 25% efficient in converting electrical energy to light, the number of photons of yellow light it emits per second is:
When light of wavelength 300 nm (nanometer) falls on a photoelectric emitter, photoelectrons are liberated. For another emitter, however light of 600nm wavelength is sufficient for creating photoemission. What is the ratio of the work functions of the two emitters?
Threshold wavelength for a metal having work function Wo is X. What is the threshold wavelength for the metal having work function 2Wo?
An electric bulb of 100 Watts converts 3% electrical energy into light energy. If the wavelength of light emitted is 6625 A, the number of photons emitted in 1 s is? h= 6.625 x 10^-34 J.sec
