1.	Assertion : When lightpasses from one medium to anotherof different density the only quantity which is unchanged is its wavelength . Reason : The wavelength of light is not related to the refractive index of the medium .
Answer» If both the assertion and reason are TRUE statement andreason is correct explanation of the assertion . If both the assertion and reason are true statement but reason is not a correct explanation of the assertion . If the assertion is true but the reason is a false statement. If both assertion and reason are false statements. Solution :In the ACT of refraction it is only the frequency that remains UNCHANGED . Wavelenght is realted to the REFRACTIVE index.Thus , both the assertionand the reason are wrong.

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
