Reflection and Interference from Thin Films
PHY 2049: Chapter 36 14 Reflection and Interference from Thin Films ÎNormal-incidence light strikes surface covered by a thin film Some rays reflect from film surface Some rays reflect from substrate surface (distance d further) ÎPath length difference = 2d causes interference From full constructive to full destructive, depending on λ d n 1 n 2 n 0 = 1

1 Range of Projectile Motion - Department of Physics at UF
www.phys.ufl.eduMost of the basic physics textbooks talk about the horizontal range of the projectile motion. It is derived using the kinematics equations: a x = 0 v x = v 0x x = v 0xt a y = g v y = v 0y gt y = v 0yt 1 2 gt2 where v 0x = v 0 cos v 0y = v 0 sin Suppose a projectile is thrown from the ground level, then the range is the distance between the ...
