the wave length in air by v=n.lemda, so 350 = 700 . wavelength so wave length = 0.5 m Now when it enters in brass, v = 3500 m/s, so new wavelength = 3500 / 700 = 5 m. So answer is option A, i.e. wavelength will be increased by a factor of 10.

lets go column wise(up to down) in the first one, the topmost value is 7. if we multiply this value with the second last value(i.e. 3), we get 21. now we must add this 21 with the second term(i.e. 8), and we get the last term that is 29. follow the same logic
