weird -_-"
a secondary 2 student asked me this question:
"when a white light is passed through a prism, what colour of refracted light will travel with the fastest speed?"
i said all the light regardless of their colours would travel with the same speed if they were travelling in the same medium. then i explained that red, orange, yellow, green, blue, indigo, violet that came out from prism would have different frequency and wavelength; violet light had the shortest wavelength and greatest frequency while red with the longest wavelength and smallest frequency, but they had the same speed, as in the wave form of light, we could follow the relation of c=f*λ. (at least this was what I learned in school, even till JC)
then i moved on to other students and the senior teacher who saw this (i.e my ex teacher) continued explaining the phenomenon to this student.
After awhile, the same student asked me with another question. But what drove me into confusion was, the student's answer for the previous question became VIOLET LIGHT??..then i asked him what explanation he wrote by answering violet light? he just said the senior teacher told him so, and he believed him more(yea, the power of school teacher)..rrr...he wrote explanation something about wavelength without stating frequency? then i asked him further whether he knew the speed of light in vacuum, and he could state 300million m/s instantly.. yup, that was the one! the speed of light was the same regardless of their colours. c'mon..
I knew violet light would be refracted to greater angle and would have greater frequency compared to other colours of visible light.. but not greater speed!
When i told him that i was pretty sure with my answer, he just wanted to hold on to what the senior teacher said regardless of explanation...huff...
a very cool way of learning huh? -_-"
yeah, it's actually normal to make mistakes in answering question, teachers are humans who are also prone to make mistake, like sometimes they(me also) don't really read the question carefully and end up in explaining other things and give other answers, but it's a pity that some learners simply miss out the point of learning itself due to nonchalance:(...

when I was a teacher too, i have experienced it. i think the problem is that the student never learned how to think or use their logic. the teacher never want be blamed so the student scared to ask the teacher's logic for the answer.
the best thing when we are be a teacher is treat the student not as a student but as a friend. I ask them to think together, to know how the logic is. sometimes we act like a stupid teacher, not to show that we don't know (even sometimes it's just my trick when i was forget :p) but to make the student not scared with us and they can tell they opinion.
I'm sure that you are talented girl n i'm waiting for your next blog :)
Good Luck always.
~God Bless~
