Short wavelength: danger
Long wavelength: safer

wavelength chart:
gamma, x, uv, visable light (VIBGYOR), infrared, micro, radio

(upside down) y = wavelength
v = frequency
h- plank's constant- 6.626 x 10^-34 Js
c- the speed of light- 3.00 x 10^8 m/s

Formulas:

c=yv
                          E=-2.178x10^-18 J {z^2/n^2}
E=hv

m= h/yv
                        E= Ef - Ei
y= hc/ E

Zeff- the effective nuclear charge isoelectronic- same # and configuration of electrons

* core- inner electrons
*valance- outter electrons
