- ordinary light is composed of seven colours where each colour has definite wavelength. so when ordinay light fallls on a thin oil floating in the surface of water, constructive interference take place for one colour at a certain point, while destructive interference occurs for the other colours in this way constructive interference for different colour takes place at different point. Hence a series of coloured fringes or pattern is seen

What is the Skin on a film of water called?
The skin on a film of water is called surface tension. It is caused by the cohesive forces between water molecules.
What is the least dense material that can not be made to float using water's surface tension?
Density is not the only property to consider when thinking of the phenomena of flotation over water using water's surface tension. Pure gold has a density of about 19 g/cm3, (water's density is about 1.0 g/cm3), and you can make small thin flakes of it to float if you previously played with them with your fingers to provide an oily film around them. This will reduce its wet-ability and reduce its contact angle. Experiment trying to make a metal clip float in water. Just squeeze the clip with your fingers to put a thin oily film around it. Then hold the clip with your index finger under it and sink your hand carefully in the water letting the clip be the last one to touch flatly the water surface. If you succeed, then try it on soapy water, using a little bit of liquid dish soap. Can you make it float again ?
How does a bubble freeze?
A bubble can freeze when the water film inside the bubble cools down rapidly, causing the water molecules to slow down and form into a solid. This process is similar to how water freezes into ice, but in the case of a bubble, the thin film of water solidifies into a delicate ice structure.
What property of water allows a needle to float on water?
Surface tension of water is the property that allows a needle to float on water. This is due to the cohesive forces between water molecules at the surface, creating an invisible film strong enough to support the needle's weight without breaking.
How can a zamboni drive on ice if there is no friction?
A Zamboni drives on ice by utilizing a surface contact pressure to melt a thin layer of ice, creating a thin film of water beneath its blades. This film of water acts as a lubricant, reducing friction and allowing the Zamboni to glide smoothly over the ice.
What is the name of the movie with a letter floating on open water on the movie cover?
Movie covers- box tops as it were are not standardized. It could well be the name of the film- Open Water. It is a tragic film.
What reaction produces a floating film on waters surface?
The reaction of soap with water produces a floating film on the water's surface. This is due to the amphiphilic nature of soap molecules, which have water-attracting and water-repelling properties. When soap is added to water, it forms a thin layer on the surface due to these properties.
Why does oil in a bowl of water get repelled when washing liquid is dropped on it?
The oil is not repelled. It is floating on the surface of the water as a thin film. Water has very high surface tension, but when soap or detergent is added to water that surface tension suddenly drops. The water surface now contracts like a punctured rubber sheet toward the remaining area of high surface tension, dragging the oil film floating on its surface with it.
What is a surface film habitat?
the answer is your mom just joking its, The surface film habitat is located on the top (surface) of the pond water. It is the habitat of air-breathing floating animals (insects) such as marsh treaders
