Light waves can be bent and reflected to form new and sometimes altered images. Understanding how light rays can be manipulated allows us to create better contact lenses, fiber optic cables, and high powered telescopes. In this unit, let's learn about reflection, refraction, defects in the human eye and the lenses we use to correct them, and ...

The energy of the wave travels in a direction perpendicular to the wavefront. If we have a point source emitting waves uniformly in all directions, then the locus of points which have the same amplitude and vibrate in the same phase are spheres and we have what is known as a spherical wave as shown in Fig. 10.1(a).

1. Ray Optics or Geometrical Optics In this optics, the light is considered as a ray which travels in a straight line. It states that for each and every object, there is an image. 2. Reflection Reflection is the phenomenon of changing the path of light without any change in the medium. 3. Reflection of Light The returning back of light in the ...

RAY OPTICS AND OPTICAL INSTRUMENTS. 9.1 INTRODUCTION. Nature has endowed the human eye (retina) with the sensitivity to detect electromagnetic waves within a small range of the electromagnetic spectrum. Electromagnetic radiation belonging to this region of the spectrum (wavelength of about 400 nm to 750 nm) is called light.

Double-slit experiment: overlapping fringes (two wavelengths) In a setup of Young's double slit-experiment, a beam of light containing a red wavelength, λ 1 = 650 nm , and a violet wavelength, λ 2 = 390 nm , create red and violet fringes on the screen. The ratio, D d = 8000 .

Question of Class 12-Interference: Young's Double Slit Experiment : It was carried out in 1802 by the English scientist Thomas Young to prove the wave nature of light. Two slits S1 and S2 are made in an opaque screen, parallel and very close to each other. These two are illuminated by another n.

Solution: A convex mirror always form virtual image, which is erect and small in size of an object kept in front of it. Focal length of convex mirror ƒ = + 15 cm Object distance u = - 12 cm Using mirror formula. Therefore, image is virtual, formed at 6.67 cm at the back of the mirror. It shows the image is erect, small in size and virtual.

Displacement of Fringes in YDSE. When a thin transparent plate of thickness 't' is introduced in front of one of the slits in Young's double slit experiment, the fringe pattern shifts toward the side where the plate is present. The dotted lines denote the path of the light before introducing the transparent plate.
