Question
using the expression 2dsinθ=λ,one calculates the values of d by measuring the corresponding angles θ in the range 0 to 90°.the wavelength λ is exactly known and the error in θ is constant for all values of θ. as θ increases from 0°( JEE ADV. 2013)
a) the absolute error in d remains constant
b) the absolute error in d increases
c) the fractional error in d remains constant
d) the fractional error in d increases
