Physics Power of lens? Definitions Examples

Answer» TION:Power of a lens is the ability to converge or diverge the RAY of light falling on it. Power of a lens is defined as reciprocal of focal length of the lens. A lens of small focal length has LARGE power of converging or diverging a parallel BEAM of light A lens formula may be defined as the formula which gives the relationship between the distance of image (V), distance of object (u), and the focal length (f) of the lens.

We know that the current in a series circuit remains the same throughout the circuit. Then what is the point to put resistors in a series circuit as the original current will pass through each one and the function of a resistor is to obstruct the flow of current? ​

Answer»

rs create a POTENTIAL DIFFERENCE across themselves that INITIATES the current to FLOW. If there is no resistor, everywhere on the WIRE will be of same potential, and thus no current can flow through them.

Find the charges on three capacitors

Answer»

acitances of three capacitors are C1= 2 μF, C2= 4 μF and C3= 6 μF and the voltage of the battery (V) is 12 V.As the capacitors are connected in PARALLEL, the equivalent capacitance is GIVEN byCeq = C1 + C2 + C3 = (2 + 4 + 6) μF = 12 μF = 12 × 10−6 FDue to parallel connection, the potential difference across each capacitor is the same and is equal to 12 V.Therefore, the CHARGE on each capacitor can be calculated as follows:The charge on the capacitor of capacitance C1= 2 μF is given BYQ1 = C1V = (2 × 10−6) × 12 C = 24 × 10−6 C = 24 μCSimilarly, the charges on the other two capacitors are given byQ2 = C2V = (4 × 10−6) × 12 C = 48 × 10−6 C = 48 μCandQ3 = C3V = (6 × 10−6) × 12 C = 72 × 10−6 C = 72 μC #NOTE:-See the diagram in photo

Explain the experiment conducted by faradi to democratic electromagnetic induction​

Answer»

Faraday's Magnetic Field Induction Experiment. When Michael Faraday made his discovery of electromagnetic induction in 1831, he hypothesized that a CHANGING magnetic field is necessary to INDUCE a current in a nearby circuit. To test his hypothesis he made a coil by wrapping a paper cylinder with wire.Michael Faraday is credited with discovering electromagnetic induction on August 29, 1831. ... He found that, upon passing a current through one coil, a MOMENTARY current was induced in the other coil— mutual induction. If he MOVED a magnet through a loop of wire, an electric current flowed in that wire.Electromagnetic induction is where a voltage or current is produced in a conductor by a changing magnetic FLUX. It may happen when a magnet is moved in a solenoid, thus changing the magnetic flux.Explanation:

Discuss the action of prism , a convex lens and a concave mirror, when a plane wavefront is incident on each of them?​

Answer»

(i) Action of the prism when a plane wave front incident on it: In adjacent figure, consider a plane wave passing through a thin prism. SINCE the speed of light waves is less in glass, the lower portion of the INCOMING wave front which travels through the greatest thickness of glass will get delayed resulting in a tilt in the emerging plane wave front.                                                       (II) Action of the convex lens when a plane wave front incident on it: In the adjacent figure, a plane wave incident on a thin convex lens; the central part of the incident plane wave traverses the thickest portion of the lens and is delayed the most. The emerging wave front has a depression at the center and therefore the wave front becomes spherical (radius = f, FOCAL length) and converges to the POINT focus F.                                                                            (iii) Action of the concave mirror when a plane wave front incident on it: In adjacent figure, a plane wave is incident on a concave mirror and on reflection we have a spherical wave converging to the focus F.Explanation:
