 EM wave Oscillating electric and magnetic fields Polarization Direction of the waves oscillation Speed of light in vacuum 3*10^8 m/s Visible light from lowest frequency (longest wavelength) to highest frequency (shortest wavelength) ROY G BV Photon Energy E = hf = h* c/wavelength Law of Reflection Angle of reflection = angle of incidence Angle of reflection and incidence are measured with respect to .. Normal Refraction bending of the light Index of refraction n = speed of light in vacuum/speed of light in medium Can n be less then 1? No, always more then 1, 1 for vacuum and air Law of Refraction n1 sin incidence angle= n2 sin refracted angle If n2>n1 ray will bend toward normal n20 Virtual image if i<0 Magnification equation m = - i/o, m- magnification factor Height of image height of object * m Upright image m>0 Inverted image m<0 Real images are inverted Virtual images are upright f for concave mirror >0 f for convex mirror <0 Lens thin piece of glass or plastic that that forms an image by refracting light Converging lenses thicker in the middle, focal point on the other side of lens, image toward the focal point Diverginf lenses thicker in the ends, focal point in front of lens, image away from focal point f for converging lens (convex) >0 f for diverging lens (concave) <0 Real images for lenses on the other side of lens, inverted Virtual images for lenses on the same side as object, upright Lens Power 1/f units of f METERS Units of power D, diopter Lenses for nearsightedness diverging Lenses for farsightedness converging
