Let me tell you a story about jacks and jills. Remember the nursery rhyme about: Jack and Jill went up the hill, to fetch a pail of water.
A slit of width d is placed in front of a lens of focal length 0.
The first diffraction maximum are separated by 2 x m. The width d of the slit is ……. Inside the medium is frequency is ……………Hz and its wavelength is ………. When they are 0.
The focal length of the lenses are …. Only one option is correct 1.
Spherical aberration in a thin lens can be reduced by: A narrow slit of width 1 nm is illuminated by monochromatic light of wavelength nm. The distance between the first 5t minima on either side of a screen at a distance of 2 m is: An isosceles prism of angle o has a refractive index 1.
The rays emerge from the opposite face: The focal lengths of the objective and the eyepiece of a compound microscope are 2. The distance between the objective and the eyepiece is The final image formed by the eyepiece is at infinity.
The two lenses are thin. The distance in cm of the object and the mage produced by the objective, measured form the objective lens, are respectively: A diminished image of an object is to be obtained on a screen 1. This can be achieved by appropriate placing: Consider Fraunhofer diffraction pattern obtained with a single slit illuminated at normal incidence.
An eye specialist prescribes spectacles having combination of convex lens of focal length 40 cm in contact with a concave lens of focal length 25 cm.Refractive index of a transparent liquid measured with a concave mirror 2 This method is based on the measurements of the actual and apparent position of the centre of curvature of the mirror.
At the focal point. when the rays are close to the optical axis—that is. the distance F V between the focal point of the mirror and the vertex is known.
