If denote microwaves, X rays, infrared, gamma rays, ultra-violet, radio waves and visible parts of the electromagnetic spectrum by M, X, I, G, U, R, and V, the following is the arrangement in ascending order of wavelength :
R, M, I, V, U, X and G
M, R, V, X, U, G and I
G, X, U, V, I, M and R
I, M, R, U, V, X and G
the correct arrangement in ascending order of wavelength is
Gamma rays < X rays < Ultraviolet rays < Visible rays < Infrared waves < Microwaves < Radio waves
5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K
A capacitor is made of two square plates each of side 'a' making a very small angle
A solution of m-chloroaniline, m-chlorophenol and m-chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of NaHCO3 to give fraction A. The leftover organic phase was extracted with d
