yes why not ,light can pass through water the answer is as follows except opaque medium light can pass through any medium but light cannot pass as much fast as in the air medium because acc:theory of huygens light can move fast in rarer medium than in denser medium

The others correctly answered the first question as yes.
Light is a form of electromagnetic radiation. It propagates as electric and magnetic fields, perpendicular to the direction of travel and to each other, rise, collapse, and transfer energy back and forth. The collapsing magnetic field induces an electric field, which in turn creates a magnetic field.
The magnetic field is affected very little by water. To the electric field, water is a dielectric medium. The field in water contains the same energy as the field in air, but its spatial distribution is different. It is more compact. The net result is that the wave propagates more slowly in water than in air or in a vacuum.
Water usually contains a lot more impurities than air, so it absorbs more light as it passes through. It also absorbs the lower frequencies more, which is why water looks blue.

Because water is transparent so light can pass through it easily. However, the light will be bent a bit so-to-speak, the technical term is refracted because of the difference in densities between water and air.

Yes light can pass through water because water is an optically transparent medium.

Yes. Else you would not see objects under water.
But when a ray of light passes from air to water, its direction will be changed according to Snell-Descartes law which states
sin i = n sin r
where n is called refractive index of water (for water n = 4/3)
i is the angle in the air between the ray and the perpendicular to the surface of water
r is the angle in the water between the ray and the perpendicular to the surface of water

It is known that the speed of light traveling through water is less than the speed of light through air.

Of course it can..haven't you ever seen the glint at the bottom of a pool. Light always shines through water, but the amount of light shining through - or how much you can see- depends on how deep the water is, or how clean it might be. I thought this was common sense....

yes, if you shine a laser through a bottle of water you will see it come through the other side.
light acts as a wave, it can travel through and around particles.
although light is diffracted (bent) by water and inside the bottle you will notice the laser bend a bit,

Yes because it is transparent. Although, because the medium of water is more condensed than air, the light will be refracted (bent)

light can pass through water......because water is not a OPAQUE MATERIAL(which does not allow light to pass through it)
