C?
A
least energy = largest wavelength so there's one answer that's a little lower in energy than C
should be the last one, notice how the waves are a bit more spaced out at D
yeah
A
|dw:1526559925785:dw| possibly but the answer they're probably looking for is photograph through solid objects since that's the most common use of X-rays
oh okay , so you can use x ray for things other than human body?
well, what leads me against answer A is that x-rays are dangerous to people and we can only be exposed to them for short periods of time under protection
you can also use x-rays to identify the properties of chemical molecules but that's probably beyond the scope of this class
A?
you there?
@Vocaloid
fluorescent lightbulbts produce UV light right so yeah I think it would be A as well
B
i think
hm I'm not 100% on this but I did some quick googling and the traffic light sensor uses IR radiation so I'm tempted to say the next frequency down (10^13) instead |dw:1526562847830:dw|
