where do you think the absorbed wave length goes, it goes to excite the vaporised metal atoms and thus the photon is absorbed, it cant mysteriously disappear, that energy must be used, those who do quanta to quark option is physics would know that d is definitely the answer. the explanation as...

i did, cuz they hav had trick questions like that in my school exams

c is incorrect beacuse they change the lamp depending on the metal being tested look in your text book, its there

14 is d, b is talking abt atomic emission

yep that sounds like wat i got

lol jbai too quick for me
