How are angles measured in light experiments?
From my experience the only time I've had to do this is when testing angles of incidence and refraction. Usually the angles of incidence are predetermined, say 20, 40 and 60 degree's. A sheet of plain white paper is placed down. A glass block is set in the middle and drawn around. Make sure you draw in your normals. Use a protractor to draw the lines which are are your angles of incidence. Then place the glass block down on the outline and use a line box with a thin slit to make the light as direct as possible. You will notice the light shining through the other side of the glass block, mark these for each incidence angle. Remove your glass block and draw proper lines for the light that was shining out of the block. From here you should be able to draw lines through your glass block outline which will connect the rays of incidence and refraction. Using your protractor you will be able to find the angles of refraction accurate to 1/2 degree i think. Other light experiments such as finding the critical angle which is a limiting angle which if passed will cause total internal reflection to occur. You can find the angle of incidence which causes this to happen in which ever medium you are testing by using the formula: refractive index = 1/sin of critical angle e.g using a diamond of refractive index 2.1 you would have: 2.1 = 1/sin C SinC = 1/2.1 C = Sin^-1 (1/2.1) C = 28.4 degrees (roughly) I hope this helped, however being more specific to which light experiment you want could help!
What Is an imaginary line perpendicular to the surface of a medium where a wave strikes it?
* base line * orthogonal projection * Versine co-ordinate The above may (or may not; the first two seem wrong and I don't think I've ever heard of the third) be correct, but I suspect the term you're looking for is surface normal or normal vector.
If two waves traveling at the same speed have different frequencies which wave has more energy?
Which ever is the highest frequency
If you have two substances that are the same size and have similar densities how ever they have different boiling points how would you separate them?
Simply heat the mixture. Given that they have different boiling points, one will evaporate before the other and thus you will have two separate substances
Do they ever light up the Empire State Building with different colors?
Yes they do for special times like when the NEW YORK GIANTS PLAY OR THE JETS THEY LIGHT IT UP:):):)

Do a hexagon have 2 right angles?
A hexagon has no right angles what-so-ever.
Are the angles of a rhombus ever equal?
Yes opposite angles are equal but not at 90 degrees.
Are paralelagrams ever rectangles?
If the all four angles in a parallelogram are right angles, then it becomes a rectangle.
Can obtuse triangle ever be isosceles?
Yes providing that the two equal angles are acute angles
Did nolan Ryan ever pitch for the angles?
yes
Are same-side interior angles ever congruent?
They can be.
Have you ever seen the multi-color reflection produce by a soap bubbles?
yes
Can a pair of adjacent angles formed by two intersecting lines ever have equal measure?
Yes, if they intersect at right angles.
What can protect you from a ghost?
Three gardian angles can protect you, also sometimes a lodestone can. If you gave three angles in your room or where ever you sleep its like three gardian angles and you will be protected :)

Do trapezoids ever have 90 degree angles?
Yes but not more than 2
