Wave Optics Test

In a Young ’s double-slit experiment, the slits are separated by 0.28 mm and the screen is placed 1.4 m away. The distance between the central bright fringe and the fourth bright fringe is measured to be 1.2 cm. Determine the wavelength of light used in the experiment

Question 1/10

Both particle and wave approaches help us understand different phenomenon

Light is schizophrenic i.e. sometimes it behaves like a particle and other times like a wave.

Light is a set of particles

Light is a set of waves
