laser beam
opaque.
you're not actually seeing through water you are seeing the light that passed through the water so if light passes through you call it seeing through
opaque objects
You would call such an object opaque.
It is called transparent object I think
Laser Beam
laser
Light beams are photon particles that can be radiated/emitted in a beam, or concentrated in a stream (also known as a LASER - Light amplification by stimulated emission of radiation.)
An object through which light cannot pass is known as opaque.
in bio we call triple beam is a scale!
opaque.
Diffraction.

Refraction
Crepuscular rays
opaque objects
Is spectrum too simplistic an answer?
