Test with two flashlights or cell phones.

Yes, it will pass through. You can test this for yourself with two flashlights set at 90 degree angle to each other.

Light waves pass through each other. In the region of overlap, the amplitudes of the waves add together. You will see interference patterns in this area. After the waves pass, they both continue on as if they never encountered each other.

Yes you can pass light beams through each other. It gets more interesting if they are laser beams but flashlight beams cross without visibly affecting each other. Try it.
