An Electromagnetic radiation has a frequency of 5.00x10^14 hx.
a) Calc its wavelength in a vacuum in metres and nanometres
b)Calc its wavelength in water
c)is this radiation visible? if so wat colour?
d) What is the index of refraction of a medium in which the speed of this radiation is 2.54x10^8m/s?
e)where would u encounter this radiation in your daily life?
My attempt...
a)c=f(wavelength) wavelength = 3x10^8/5x10^8
=600nm and 6.00x10^-7 m
b)n=1.33 in water ?=6.00x10^-7/1.33
wavelength =600nm =451nm
wavelength in median ??
c)yes this radiation is visible and according to the visible spectrum, 590-610nm is orange so its at 600nm so it is orange.
d)i cannot do this question, can anyone help me??
e)same with this one
