#2.439xx10^16Hz#, rounded to three places of decimal.

Explanation:

Frequency #nu#, wavelength #lambda# and speed of light #c# are connected to each other by the expression
#c=nulambda#
Inserting give number and taking #c=3xx10^10cms^-1#, CGS units
#3xx10^10=nuxx1.23xx10^-6#, solving for frequency

#nu=(3xx10^10)/(1.23xx10^-6)#
#=2.439xx10^16Hz#, rounded to three places of decimal.
