TERM 1 Why there are both electric and magnetic fields in a light wave DEFINITION 1 bla TERM 2 How the speed of light is related to the fundamental constants of electricity and magnetism DEFINITION 2 The Huygens-Fresnel principle (named for Dutch physicist Christiaan Huygens, and French physicist Augustin-Jean Fresnel) is a method of analysis applied to problems of wave propagation (both in the far field limit and in near field diffraction). TERM 3 How to describe the propagation of a sinusoidal wave electromagnetic wave DEFINITION 3 Central bright band. 85% of light intensity goes into the bright band. Width of pattern is INVERSELY proportional to the slit size. Cancellation interference occurs when the d=m(lambda)/sin(theta) is a half-factor of (lambda) sin(theta) = m (lambda) \ a (dark fringes) y(m) = x (m*lambda)/a (for y(m) TERM 4 What determines the amount of power carried by an electromagnetic wave DEFINITION 4 E(p) = E(0) [sin(B/2)] / (B/2) [amplitude in single slit] I = I(0) [sin(pi*d*(sin[theta])/(lambda)) / (pi*d*sin(theta) / lambda)] ^2 [intensity in single slit] B = (2pi / lambda)* d *sin(theta) [phase angle B] TERM 5 How to describe standing electromagnetic waves DEFINITION 5 ...
