QAIPMT-2003-Ch-2666: NEET 2003 Chemistry - Class 11 AIPMT-2003-Ch-2666 Solution: The value of Planck's constant is \(6.63 10^{-34}\) J s. The…

The value of Planck's constant is 6.63×10−346.63\times10^{-34} J s. The velocity of light is 3.0×108 m s−13.0\times10^8\ \text{m s}^{-1}. Which value is closest to the wavelength in nanometers of a quantum of light with frequency of 8×1015 s−18\times10^{15}\ \text{s}^{-1}?

Multiple Choice Options

  • A 2×10−252\times10^{-25}
  • B 5×10−185\times10^{-18}
  • C 4×1014\times10^1
  • D 3×1073\times10^7

Step-by-Step Verified Solution

v = c/ _ _ = c v = 3 _ 10 8 8 _ 10 15 = 37.5 _ 10 -9 m = 37.5 nm � 4 _ 10 1 nm
