A) infrared rays
B) \[\gamma -\]rays
C) visible light
D) \[X-\]rays
Correct Answer: B
Solution :
Shorter wavelength is of \[\gamma -\]rays as per data Wavelength of \[\gamma -\]rays\[=0.01\overset{\text{o}}{\mathop{\text{A}}}\,\]to\[1\overset{\text{o}}{\mathop{\text{A}}}\,\] Wavelength of \[X-\]rays\[1\overset{\text{o}}{\mathop{\text{A}}}\,\]to\[100\overset{\text{o}}{\mathop{\text{A}}}\,\] Wavelength of visible light \[=4000\overset{\text{o}}{\mathop{\text{A}}}\,\]and\[7900\overset{\text{o}}{\mathop{\text{A}}}\,\] Wavelength of infrared \[=7900\overset{\text{o}}{\mathop{\text{A}}}\,\]to\[{{10}^{7}}\overset{\text{o}}{\mathop{\text{A}}}\,\]
