The frequency is =2*10^18Hz=21018Hz

Explanation:

Apply the equation

"Frequency" xx " Wavelength "= " Speed"Frequency× Wavelength = Speed

fxx lambda=cf×λ=c

The wavelength is lambda=1.5*10^-10mλ=1.51010m

The speed is c=3*10^8ms^-1c=3108ms1

The frequency is

f=c/lambda=(3*10^8)/(1.5*10^-10)=2*10^18Hzf=cλ=31081.51010=21018Hz
