Using the Planck's Equation, comes:
[tex]E=hf \\ E=6.63*10^{34}*5.48*10^{14}*J \\ \boxed {E=36.3324*10^{20}*J}[/tex]

The energy of the photon in joules, given that it's has a frequency of 5.48×10¹⁴ Hz is 36.33×10¯²⁰ J
Data obtained from the question
 Frequency (f) = 5.48×10¹⁴ Hz
 Energy (E) =?
How to determine the energy
 Planck's constant (h) = 6.63×10¯³⁴ Js
 Frequency (f) = 5.48×10¹⁴ Hz
 Energy (E) =?
The energy of the photon can be obtained as follow:
E = hf
E = 6.63×10¯³⁴ × 5.48×10¹⁴
E = 36.33×10¯²⁰ J
