electromagnetic radiation Flashcards
1
Q
what are the types of EMR, and what do we focus on
A
radio, micro, UV, infrared, visible, and gamma. Focus on visible (light)
2
Q
what type of wave is light
A
transverse
3
Q
wavelength
A
length of wave, crest to crest
4
Q
frequency
A
of waves passing a point per second (higher wavelength= lower frequency)
5
Q
What are the two equations for light
A
C=λ v (C= 3e8 m/s, λ=wavelength (m), v=frequency(s))
E=hv (E=energy of a photon (J), H=6.626e-34, V=frequency (s-1/Hz))
