#nu= 6.7xx10^11\ sec^-1#

Explanation:

# nu=c/lambda#

#nu -> "frequency in "sec^-1#
# c -> "speed of light = " 2.998xx10^8 \ m //sec#
# lambda ->"wave length = " 4.5xx10^-4 \ m#

#nu=(2.998xx10^8\ m//s)/(4.5xx10^-4\ m)#

#nu=(2.998xx10^8\ cancel(m)//s)/(4.5xx10^-4\ cancel(m))#

#nu= 6.7xx10^11\ sec^-1#
