can cause the observed ripples in the Cosmic Microwave Background?

Yes light is effected by gravity and changes in the medium it is passing through. like on a hot day when you think you see water on the road the hot air rising off the road is bending the light rays when a gravitational feildchanges the direction of enough light rays from a distant source you can see a duplicate image and in kind some images you can not seeas their light is being bent from our line of sight.

No, gravitational lensing does not cause the "ripples" in the Cosmic Microwave Background Radiation or CMB for short.
The Cosmic Microwave Background Radiation comes from all sides of the Universe. It was emitted when the Universe was just 300-400 thousand years old.
The slight differences in intensity, what you are calling ripples, are called microwave anisotropies, and show us the distribution of matter at the time the CMB was emitted, and how that distribution evolved into superclusters and voids.
Superclusters are where most galaxies exist; as an example, our galaxy is part of a cluster of galaxies, which includes the galaxy of Andromeda; our local group (or cluster) is part of a supercluster along with other groups of galaxies.
Voids are just empty space; no individual galaxies, or clusters or superclusters.

Only if the surge is close enough to the intervening galaxies can one observe the ripple effect however there is an another method for viewing such an event.

I don't know about gravitational lensing, but the Suynaev-Zel'dovich effect (inverse Compton scattering off galactic clusters) might cause more 'dark' regions than just the CMB by itself by scattering the CMB photons.

the residual 3 degrees kelvin mic.rowave radiation from big bang,like light ,is deflected in a gravity field.

Ok, this question is too deep for me!
