What is Brewsters angle when the light in the air is reflected off a surface of a lake?
Type your answer here... Brewster's Angle is also known as "polarizing angle" and it can be measured by using the mathematical expression: BA = arctan n Where BA stands for Brewster's Angle and n is the numerical index of refraction of the medium of the surface in question. Lakes normally contain fresh water and the index of refraction for water is 1.33 Using the equation, the arctan of 1.33 = 53.1 degrees. Therefore, the BA of the surface of a lake is 53.1 degrees.
Why the lake is greenish blue?
The color of a lake may just be the color of the sky, reflected in the lake, but if the water itself is actually greenish blue, that is caused by algae.
When a raindrop hits the surface of a lake circular surface waves form What is true about these surface waves?
The surface waves cannot be classified as transverse or longitudinal waves.
How can you tell if sunglasses is polarizing?
Instead of rather a complicated and scientific method, you may simply figure it out with two pairs of glasses. Specifically, hold up both lenses and try looking through them both, then rotate one pair 90 degrees. If the sunglasses are polarized, you will not be able to see through these two lenses once you do this. If you do, one of the lenses is not polarized. What's more, try ooking through your lenses (holding them in your hands away from your face) at a window, TV screen or lake with intense glare. Rotate the glasses in a circle facing the glare. The intensity of the glare should change when you rotate your glasses; otherwise, it's not polarized.
What is the definition of capillarity in terms of Physics?
Physics defines capillarity as the action of a liquid being distorted by a solid hitting its surface. Examples of this include the ripples made by a stone hitting the surface of a lake.
Why do Fisherman wear polarizing sunglasses?
Fishermen wear polarizing sunglasses so they can negate the effect of the suns glare on the surface of the water in order to sight fish. This is a benefit when fishing on a lake or river and the glare on the water is preventing you from seeing the fish in the water.
How polarised sunglasses work?
Polarized lenses are used in sunglasses to reduce glare from reflective surfaces such as the surface of a lake or the hood of a car. They accomplish this feat through a process called polarization, much like a venetian blind controls sunlight through a window.
Can you explain this question to me... The rate of evaporation from the surface of a lake would be increased by?
an increase in the surface area of the lake
Why can you see your own reflection in acalm lake but not in a sea?
we can see our reflection in calm lake because the water is not moving and in sea the water is moving very fastly
When does a surface reflect lights most clearly?
A surface will reflect light most clearly when that surface is completely smooth. Example of clear reflection: Look at the reflection on a lake when there is no wind or anything causing ripples or waves. The reflection is clear and objects reflected can be seen clearly. Example of distorted (unclear) reflection: Look at the same lake on a very windy day when there are many waves and other ripples on the waters surface. The reflections coming off the waters surface are hard or imposable to see due to the distortion of the reflection.

What may be seen on surface of lake?
You can see many things on the surface of a lake such as algae, plastic crap, protruding sticks and rocks, trees, the reflection of light, ducks, swans, jumping fish, tadpoles, small fish, and other items of the sort. Keep in mind, though, it depends on what the season is , and where the lake is located.
Why is polarization good for sunglasses?
Polorized sunglasses will reduce glare!Example...if you wear polorized glasses to the lake...you will be able to see into the water instead of the glare on top of the water!The uv protection isn't better or worse with polorized.......it basically does the squinting for you!Most people that spend alot of time on the water will use polorized..fishing,etc!They are great for driving to...just becareful if your window is already polorized you wont see through it, if you have polorized glasses on..it will look distorted!you wont be able to read digital clocks and stuff as well!!

Which is bigger Lake Ontario or Lake Garda?
Lake Ontario is larger with a surface area of 19,000 km2, while Lake Garda only has a surface area of 369.98 km2.
Where is the wordls largest freshwater lake?
Lake Superior - by surface area Lake Baikal - by volume
What lake can you find a Pokemon?
You can find Pokémon on the water surface of any lake.
