The frequency order for X-rays ( A), γ-rays (B), UV rays (C) is
B > A > C
A > B > C
C > B > A
A > C > B
A.
B > A > C
The frequency range Gamma-rays lies in between 1028 to 1023 Hz
The frequency range UV rays lies in between 1016 to 1020 Hz
The frequency of UV rays lies in between 1015 to 1019 Hz
The frequency order for given electromagnetic waves is as follows
νγ-rays > νX-rays > νUV
B > A > C
