There are some objects through which light can travel, others it cannot.
Light is a part of the electromagnetic spectrum and each part has a certain energy level. The energy required to travel through an object varies with the make up of that substance.
The property an object has for allowing the passage of electromagnetic radiation to pass is called its transparency.
An object may not allow light to pass but allow x-rays to pass because x-rays have more energy than light. There fore human flesh, for instance, is opaque to light but transparent to x-rays.
There are other things involved but this is a simplified explanation.
light can travel through a vacuum whereas sound cant
light cant travel through opague materials, or anything you cant see through.
Dark objects do not reflect light. Light is absorbed by them.
It tells us that light only travels in straight lines and cant travel through most objects.
Why cant sound travel through empty space

light can but sound cant as there is no air
You cannot see your reflection in all objects that reflect light because of diffuse reflection.
If you're asking for what light cannot touch, then there is nothing. Other than air, light acts on everything. If light did not reflect off of objects, they would be invisible. EDIT: Visible light cannot penetrate a mirror. If the mirror is of suitable quality, most of the light should be reflected, with the remainder being absorbed. EDIT: light acts on air, it does not act on a vacuum, it travels straight thru it. with air however, light is difracted
Why cant sound travel through empty space
Ocean
As during a thunder storm there is very little light from the sun. so the light cant travel through the rain drops. thus making it impossible to have a rainbow
sound can't travel through a vacuum. or a place without air.
