The wavelength of the light that falls on the slit = 5.692 × 10⁻⁴m
Here we have
Fringe. separation. = 2.90 mm = 0.0029 m
Slit. separation. = 0.420 mm = 0.00042 m
Distance. from slits to. screen. = 2.14 mm = 0.00214 mm
Wavelength. is given by the following relation.
Wave length = Fringe separation × slit separation /Distance from slits to screen
Therefore;
Wave length = 0.0029 m × 0.00042 m/0.00214 mm = 5.692 × 10⁻⁴m
In a broader sense, the term "light" can apply to electromagnetic radiation of any wavelength, whether visible or not. [4] This definition of light includes gamma rays, X-rays, microwaves, and radio waves. The main characteristics of light include intensity, polarization, frequency or wavelength spectrum, and propagation direction. One of nature's basic constants is the speed of light in a vacuum, which is 299 792 458 meters per second (m/s). [6] Visible light, like all forms of electromagnetic radiation, is propagated by massless elementary particles called photons, which serve as a representation of the electromagnetic field's quanta and can be thought of as both waves and particles. Modern physics places a lot of emphasis on the study of light, or optics.
