sir can u please tell me the difference between the two spectra,interms of colors etc?

what is the use of plane polarizing light?

i was working with a spectrometer and the aim of the experiment was to find the refractive index of a prism for various colors. i was asked specifically to use mercury vapor lamp and was insisted not to use sodium vapour lamp. why is it so?

what is the mistake in my approach? why not take change in potential energy as work done?

sir, the string here has considerable mass.let us consider the part x(as i have mentionedin prob) and l-x seperately.why isn't the weight due to upper part pushing down the lower part and contributing to tension? isnt it just like a block placed over another as in this case it is clear that...

a string of length l and mass m hangs freely from a fixed point calculate the velocity of the transverse wave at any position sol: mass per unit length is m/l let there be a point on the string at a distance x from free end tension at the point=wt of the string per unit length*part of the...

Homework Statement A spherical shell of radius R with uniform charge Q is expanded to a radius H.find the work done by electric forces during the shell expansion given answer is 1/(8pi epsilon) *Q^2(1/R-1/H) my attempt work=-change in P E =Q(V1-V2) =1/(4pi epsilon)...

A train is moving towards north at one place. it turns towards north east. here we observe that the radius of curvature of outer rail will be greater than that of inner rail why?pls explain velocity and radial acc. are the same and radius of curvature=v^2/a normal

please explain me,how the angle is pi what does the statement the object is always moving towards origin imply?

An object is moving in 3D space with position vector vectot r=(x)i+y(j)+z(k) and velocity vector v=a(i)+b(j)+c(k) i,j,k are unit vectors along x,y,z axes If the object is always moving towards origin, then (a) a/x =b/y = c/z (b) (a/x)(b/y)(c/z)<0 (c)ax+by+cz<0 (d)ab/xy >0 x,y,z,a,b,c...

is this possible with vectors also. my teacher is no ordinary.the probs he would give us would look ordinary,but the concept they reveal would be extra-ordinary...

Hi, I'm actually working on a problem in Rotational mechanics. I'll just hint the problem. In a rotating body,tangential acc=(radius)angular acceleration. velocity=(radius)angular velocity.thus, [tangential acc/angular acceleration] =[velocity/angular velocity] can we use the...

I'm sorry I cannot get it...

Hi, I'm encountering problems in my tests about young's double slit experiment and in many of those I'm finding the source executing simple harmonic motion (whose equation is given ) and we are asked to calculate the equation of motion of central bright fringe,max no. of fringes that can be...
