The fringe width `(beta)` of a diffraction 2 pattern and the slit width 'd' are related as:

(A) `beta prop(1)/(d)`
(B) `beta prop d `
(C) `beta prop sqrt(d)`
(D) `beta prop(1)/(d^(2))`

Angular width (beta) of central maximum of a diffraction pattern on a single slit does not depend upon

Force F and density d are related as F=(alpha)/(beta+sqrtd) , Then find the dimensions of alpha and beta

Name the types of interaction or intermolecular forces of which potential energy-distance function are given below (a) Eprop (1)/ (r ) (b) E prop (1)/(r^(2)) (c ) E prop (1)/(r^(3)) (d) E prop (1)/(r^(4)) (e) E prop (1)/(r^(6)) .

Differentiate between Prop roots and stilt roots

For the reaction A + 3B to C + D rate of reactions prop [A][B]

If the distance of a given point (alpha,beta) from each of two straight lines y = mx through the origin is d, then (alpha gamma- beta x)^(2) is equal to (a) x^(2) +y^(2) (b) d^(2)(x^(2)+y^(2)) (c) d^(2) (d) none of these

A particle is projected up an inclined plane of inclination beta at na elevation prop to the horizontal. Show that (a) tan prop = cot beta + 2 tan beta , if the particle strikes the plane at right angles (b) tan prop = 2 tan beta , if the particle strikes the plane horizontally.

Assertion: Distance between posittion of bright and dark fringe remain same in YDSE. Reason: Fringe width beta=(lamdaD)/(d) .

Study the graph given below and choose the option that is correctly describing the relationship between dissolved oxygen (DO) and biochemical oxygen demand (BOD) : (a) DO prop 3BOD (b) DO prop 2BOD (c) DO prop 1/(BOD) (d) DO prop BOD
