The equivalent capacitance for capacitors connected in series is given by
or,
The equivalent capacitance for the capacitors connected in parallel is given by
So, if we connect four 1 mF capacitor in parallel then the equivalent capacitance will be
So, if we connect four 1 mF capacitor in series then the equivalent capacitance will be

The electric field lines show the strength of the field in the region.
It is clear that the strength of the electric field due to the charge Q2 is twice of that of the field due to the charge Q1.
The electric field due to the charge Q1 at a distance 'r' is given by
So, the ratio of both the charges will be
But both the charges are of opposite nature. So,

Plane coherent light waves with wavelength 565 nm are incident on two narrow parallel slits positioned a distance d = 1 mm apart in a plane parallel to the incoming wavefronts. The interference pattern is observed on a screen parallel to the original wavefronts at 1 m from the two slits. One of the slits is covered on the illuminated side by a glass slide of 0.1 mm thickness with refractive index 1.5. a/ What is the phase difference ∆φ...

Question 6: What percentage error would result from miscounting the bars by one? EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a known...
(a) A possible means for making an airplane invisible to radar is to coat the plane with an antireflective polymer. If radar waves have a wavelength of 3.08 cm and the index of refraction of the polymer is n = 1.80, how thick (in cm) would you make the coating? (Assume that the index of refraction of the plane is higher than that of the coating. Also assume that the radar waves are normal to the surface of the coating....
