A gas at 298 K is shifted from a vessel of 250 cm3250 cm3 capacity to that of 1L capacity. The pressure of the gas willAccording to Charles’s lawWhich of the following relations for expressing volume of a sample is not correctIf n(μ)=100, n(A)=50, n(B)=20 and n(A∩B)=10 then n[(A∪B)c]=
Duration of day time is greater than night time due toWhen a light wave travels from denser to rarer medium, its
P) velocity decreases R) wavelength increases Q) frequency remains unchanged
When a light ray suffers reflection, at the interface between air and glass, the change of phase in the reflected wave is equal toWhen a light wave travels from denser to rarer medium, its
P) velocity decreases R) wavelength increases Q) frequency remains unchanged
beamA beam of white light is incident on a hollow glass prism. Then the light emerging from the prism gives from 0° and 90°
Dispersion is the term used to describe :If the refracting angle of a prism is 60°60° and minimum deviation30°30° , the angle of incidence will beOne atmosphere is numerically equal to approximately
