Hello again! Just a few multiple choice questions.
When blue light strikes an opaque object whose resonant frequency is the same as the frequency of the blue light what happens? ( Choose as many as apply)
A) The amplitude of the vibrations of the electrons in the object becomes larger
B) The object becomes warm
C) The blue light is absorbed without reemission
D) The blue light is reflected by the electrons in the object
E) The blue light is transmitted through the object
I think A, B, C

Which of the following is true of ultraviolet light? (Choose as many as apply)
A) It has a higher frequency than that of visible light
B) Unlike visible light, it is not an electromagnetic wave
C) The Earth's atmosphere is completely opaque to it
D) It is responsible for sunburns.
I think A & DI don't want you guys to give me the answers, I'd just like to know if I'm understanding this right. Thank you for any assistance :)
