Vocaloid:

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

zarkam21:

oh okay , so you can use x ray for things other than human body?

Vocaloid:

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

Vocaloid:

you can also use x-rays to identify the properties of chemical molecules but that's probably beyond the scope of this class

Vocaloid:

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|
