How much is an obtuse angle?
Any angle larger that 90 degrees and less than 180 degrees is obtuse.
What is the complement of an angle whose measure is 72.354 degrees?
The complement is (90 - the angle) or: how much you have to add to the angle to make 90 degrees.(90 - 72.354) = 17.646 degrees.
How much degrees does an acute angle have?
less than 90 degrees
How much does a right angle mesure?
It is 90 degrees
How much degrees does a right angle measure?
90
Does clear glass refract light?
Clear glass does refract light when light passes from another medium like water to clear glass. But there is an exception. If the ray of light were to pass through water and hit the clear glass straight or at 90 Degrees to the surface, then clear glass does not refract the light.
What happens if a torch is shone at 90 degrees under water. would it refract?
If the torch light is fully underwater it could be held at any angle between 180 degrees before it refracted, as refraction involves light passing between two media with different densities. If water is constantly the same density it will not bend the light.
Does a periscope work to refract light?
Periscopes work by reflecting light, not refracting it. Light enters the top of the periscope and is reflected through 90 degrees by either a plane mirror or a right angled prism (TIR) and travels down the tube where it is reflected again along the eyepiece to the eye.

When does light cross a boundary but not refract?
This happens if the light makes a 90 degree angle with the boundary (hits is straight on), so it just keeps going in a straight line.
How much degrees is in a right angle?
A right angle is 90 degrees
How much degrees is a straight angle?
90 Degrees
How much is an obtuse angle?
Any angle larger that 90 degrees and less than 180 degrees is obtuse.
Can you bend an led light strip 90 degrees?
yes
