What will two polarizing filters overlapped at right angles do?
Block all light.
When two polarizing filters overlap at right angles why does the area of overlap look dark?
All particles of light (called photons), have a polarization. This is a tiny imaginary arrow that every photon has, and it points in a direction sideways to the way the photon is moving.A polarizing filter also has an imaginary arrow that points sideways to it's surface. When photons hit a polarizing filter, only the photons whose arrow is pointed in the direction of the filter are let through. This also means that all the photons that go through a polarizing filter have their arrows pointed in one direction. We say that the light that gets through is polarized.Now, if we add another filter after this one which has an arrow that is at a right angle from the polarized photons, no photons can pass through the second filter. That's why the area of overlap looks dark.P.S. : If we add a filter at 45 degrees relative to both filters in between, some of the light gets through! This is a consequence of quantum mechanics. Check out an introductory book on quantum physics to find out why.degree in-between these 2 filters, some of the light gets through!
How much light passes through two polarizing filters held at right angels to each other?
None
Can you draw a triangle with 2 right angles?
Yes you can. The problem is on what surface you draw the triangle. On a plane this would be impossible, but if you do it on a spherical surface then you can even draw a triangle with 3 right angles.
If two polaroid filters are held with their polarization axes at right angles to each other the amount of light transmitted compared to when their axes are parallel is?
Zero.
The angles in a rectangle are all?
... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.
How many right angles do a kite have?
A kite has 4 right angles (all angles of the kite are right angles), since the kite is parallel. If the kite was cyclic, then 2 right angles. And if normal kite, then 0 right angles.
Do a rectangle have right angles?
Yes, a rectangle has right angles. In fact it has 4 right angles.
Do all angles of a rectangle are right angles?
Yes, the 4 inside angles are right angles
How many angles and how many right angles in a square?
4 right angles, no other angles.
How many angles and right angles does a regular hexagon have?
It has 6 angles, none of which are right angles.
Does a kite always have 4 right angles?
No, the angles aren't right angles.
