well that is a very complicated question and you can get very detailed on both sides of te argument but i would say no because float would mean it would float on air or another substance on to substance and it always travels the same way at the speed light and is not affected by gravity on earth or not gravvity in space
To varying degrees, of course it can. You can see through a glass of water, therefore the light must be passing through the water.
Different liquids will block different amounts and different types of light but most (very likely all...but I won't commit to that) will allow some light of some kind to pass through, at least if we count UV and the like.
So yes, light can very easily travel through liquid. Light will slow down through a liquid, however - an effect we know as refraction. This accounts for why partially submerged objects appear broken or distorted as they enter the water.
Light can travel through undistorted

Light waves travel fastest through vacuum, at nearly 30 million meters per second. Light travels more slowly through other substances such as air and water, and can be absorbed.
Sound (and vibration) are a wave system of sequential compressions and rarefactions of a material. These waves are mechanical and do need a substance through which to travel. They cannot travel through a vacuum.

Squid ink and blood are a couple that come to mind.
Sound waves need a medium to travel through - the medium may be solid, liquid, or gaseous. Electromagnetic waves (including light) can also travel through empty space.
The speed of light is always the same, the different speeds associated with a liquid are due to the absorbing and emitting of the light within the substance as it travels through it, which is not necessarily 'c' (2.99792458x10^10 cm/sec).
I wouldn't say to well
no if an object is OPAQUE then light can't travel through it (unless it has a hole in it)
Light does travel through a vacuum.
it cant travel through light.
Light will not travel through an opaque sponge.
light can travel through a vacuum whereas sound cant
yes
