A) \[a<b;b>c\]
B) \[a>b;b>c\]
C) \[a<b<c\]
D) \[a=b=c\]
Correct Answer: A
Solution :
| [a] Frequency range of \[\gamma -ray,\] |
| \[b={{10}^{18}}-{{10}^{23}}Hz\] |
| Frequency range of X-ray, |
| \[a={{10}^{16}}-{{10}^{20}}Hz\] |
| Frequency range of ultraviolet ray, |
| \[c={{10}^{15}}-{{10}^{17}}Hz\] |
| \[\therefore \]\[a<b;b>c\] |
