http://www.rocketmime.com/astronomy/Telescope/Magnification.html im studying from above how image is magnified in a binocular or telescope. In binocular say 7X. can you say light is amplified or jus magnified? if amplified, is it 7 times? if just magnified and not amplified. how come using binocular on the sun can blind person faster than naked eye? also for example you are viewing buildings at daytime and suddenly you see the sun reflected from the building glasses... is the effect like looking at the sun directly.. or how much reduction if not same exposure?
