Light is estimated to travel at the rate of approximately 300,000 km. per second. It can pass through anything that is transparent (objects which can be clearly seen through such as glass), partially through anything that is translucent (objects which can only be partially seen through such as white paper), but cannot pass through things that are opaque (objects that cannot be seen through such as a brick wall)...
