dicuss why it is difficult to classify water as transparent,translucent and opaque?

Because there are different types of water.  Those with clear water don't have much going on biologically.  You could say the exact opposite for opaque water.

The liquid is transparent if you can see the pencil. The reason the pencil looks that way is refraction. The light travels differently through the water, so it bends and doesn't go in the same straight line that it was. So you see half in the air, straight, and half in the water, at a different angle. Try putting the pencil in slowly. You will see it is only the part that is in the water that looks bent. Other liquids (oil, rubbing alchol) bend the light different amounts so the angle is different. Try it and see.

false. Are you looking for others to answer your homework? just type in diatoms and read about them. They are facinating, especially under the microscope. You may have some diatoms in your pool filter-called DE, diatomaceous earth, they help keep the water crystal clear. Read about them.

Because there is a "serrated" surface embedded in the print that defracts the light and scatters it into its different components.  The principal is the same as a Prism.  Visible light is made of many colors, from blue to red and if you put white light into a prism it will separate it into the many colors of the rainbow.  The reason you can see the different colors on the seal is because when you move the bill around, you are looking from different angles and seeing that particular frequency of the light spectrum

its the way the light reflects of the bits of water

The water makes it harder for light to reach the fabric. Kind of like when you look at the ocean and the water is a dark blue the farther out you look.

It is the ability for a liquid to pass through a seemily watertite skin

Water magnifies the power of UV rays in light.

I think they've misunderstood.its not speed you are asking about? Depends on the density of the air. light wont travel as far in foggy or smokey conditions as it will under clear conditions.water and air are basically the same thing, different density. That's why it is dark at the bottom of the ocean. It is too dense to penetrate Under clear conditions the distance light will travel if indefinite as far as we know as long as there is nothing interfering or blocking the source

yes......\nlight can travel with or without a medium... water is a medium.... can be considered a transparent material..... so light can pass through water... in other mediums, liike opaque and translucent, light may either be absorbed or half absorbed and half transmitted...

Light hits water droplets and gets divided into seperate colors like the prism effect.

The light still comes through because both water and glass are transluscent, but there's two reasons why seeing clearly is difficult.\n\n1) Light travels through water and glass at different speeds, and so get bent when it transitions between them.\n2) If the water hits the window and sticks like a droplet, it acts like a lense or a sort of prism and also bends the light.\n\nThe more the light gets bent, the more distorted the image gets, and the harder it becomes to make sense of it, i.e to "see clearly."

This has to do with the optical properties of water as it enters a new so-called phase; from liquid to solid. The liquid and solid state of water are two macroscopic phases, which means that the collective behaviour of the water molecules changes drastically as the temperature, in this case, drops below T = 0 degrees Celsius. As the molecules behave differently in the solid state than in the liquid state, e.g. they reflect light in a different manner due to their structural arrangement, it is not surprising that water has a different color when it freezes compared to when it is a liquid.

Actually, snow flakes are clear! It is the reflection of light off the crytalized (frozen) water dropplets that gives the appearance as white..

water is denser than wood

Each pixel on the screen is composed of three colours (red, green, blue) that each vary in intensity and blend together to give the illusion of one pixel colour due to their small size.\nWhen a drop of water lands on the screen, it magnifies the individual pixel colours such that they appear to be distinct.

Some light can pass through a translucent object, like wax paper; while no light can pass through something opaque, like construction paper.
