Question

Identify the INCORRECT statements from the following:
A. Notation ${ }_{12}^{24} \mathrm{Mg}$ represents 24 protons and 12 neutrons.
B. Wavelength of a radiation of frequency $4.5 	imes 10^{15} \mathrm{~s}^{-1}$ is $6.7 	imes 10^{-8} \mathrm{~m}$.
C. One radiation has wavelength $=\lambda_1(900 \mathrm{~nm})$ and energy $=\mathrm{E}_1$. Other radiation has wavelength $=\lambda_2(300 \mathrm{~nm})$ and energy $=\mathrm{E}_2 \cdot \mathrm{E}_1: \mathrm{E}_2=3: 1$.
D. Number of photons of light of wavelength 2000 pm that provides 1 J of energy is $1.006 	imes 10^{16}$.
