 formula for magnification m=-i/o what type of image does a diverging (convex) mirror/lens create virtual upright image what type of image does a concave mirr/ lensor create if object is placed beyond focal point, if object is place inside focal point? beyond- real inverted image inside- virtual upright image does convex mirror have a (+) or (-) focal length? how about concave mirror? convex (-) focal length concave mirror (+) formula for index of refraction n=c(speed of light)/v (speed in the medium) Snell's law n1sin()1=n2sin()2 under what conditions will light undergo total internal reflection when light travels from higher index to lower index at angle greater than critical angle does converging lens have a (+) or (-) focal legth? how about diverging lens? converging (+)diverging (-) (t/f) the real side of lens is the side opposite from the light source true formula for lens power P=1/focal length formula for calculating the energy of a photon E=hf or E=hc/wavelengthh-Planck's constant photoelectric effect electron are emitted by a metal that is exposed to light of sufficiently high energy formula for kinetic energy of an emitted electron KE=h(f-fT) where fT is theshold frequency what happens when a electron jumps from a higher energy level to lower (orbit)? will emit a photon whose energy equals the difference in energy btwn the two orbits. what happens to atom's mass and atomic number when an alpha particle is emitted (alpha decay) atomic number -2mass number -4 what happens to atomic /mass number after beta- decay?how about beta+ (positron) decay ? beta-, the atomic number +1beta+, th atomic number -1 no change of mass number what happen to atomic/ mass number after gamma decay no change to both Authorallenwhycheng ID59716 Card SetMCAT PHYSICS 3 Descriptionstudying to be a doctor Updated2011-01-14T03:35:55Z Show Answers
