One requires 11eV of energy to dissociate a carbon monoxide molecule into carbon and oxygen atoms. The minimum frequency of the appropriate electromagnetic radiation to achieve the dissociation lies in An LC resonant circuit a 400 pF capacitor and a 100 pH inductor. It is set into oscillation coupled to an antenna. The wavelength of [...]

A travelling wave is partly reflected and partly transmitted from a rigid boundary. Let a(i),a(r)and a(t) be the amplitude of incident wave, reflected wave and transmitted wave and I(i),I(r)and I(t) be the corresponding intensities. Then choose the correct alternatives A travelling wave is partly reflected and partly transmitted from a rigid boundary. Let a(i) a(r)and [...]

Equations of a stationary wave and a travelling wave are y1=a sin kxcos ωt and y2 =a sin(ωt−kx). The phase difference between two points x1 = 3k/π and x2= 2k/3π are ϕ1 and ϕ2 respectively for the two waves. Find the ratio ϕ2/ϕ1 is String 1 has twice the length twice the radius twice the [...]
