formula for magnification
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)
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?
(t/f) the real side of lens is the side opposite from the light source
formula for lens power
formula for calculating the energy of a photon
E=hf or E=hc/wavelength
electron are emitted by a metal that is exposed to light of sufficiently high energy
formula for kinetic energy of an emitted electron
) where f
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 -2
mass number -4
what happens to atomic /mass number after beta
decay?how about beta
(positron) decay ?
, the atomic number +1
, th atomic number -1
no change of mass number
what happen to atomic/ mass number after gamma decay
no change to both
