Vedclass · Answer

(B) $1$. According to the de Broglie relation,$\lambda = \frac{h}{mv}$. Since the mass of an electron is much smaller than that of a proton,for the same speed,the electron will have a longer wavelength. This statement is true.$2$. Violet light has a shorter wavelength (approx. $380-450 \ nm$) compared to red light (approx. $620-750 \ nm$). Therefore,the statement that violet radiations have a longer wavelength than red radiations is false.$3$. Energy $E = \frac{hc}{\lambda}$. Since $E \propto \frac{1}{\lambda}$,light with a longer wavelength $(600 \ nm)$ has lower energy than light with a shorter wavelength $(500 \ nm)$. This statement is true.$4$. Atoms emit radiation at specific discrete frequencies,resulting in a line spectrum. This statement is true.

Which of the following statements is $NOT$ true?
