Ans:
Red colour of visible light has longest wavelength.
Rydberg constant (Rydberg): A constant that governs the relationship of the spectral line features of an atom by the Rydberg formula. For hydrogen, it is about 1.097 x 10 7 m
It explains that when an object is immersed partly or completely in a liquid, it loses in weight similar to the weight of the liquid displaced by it. Let w1 be weight of an obje
