What is refraction? How and why does it occur? Why does light change its speed as it passes from one medium to another. Explain the behavior of light as it goes from a denser (higher refractive index) to a lighter (lower index of refraction) and vice versa.
implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves).
In the absence of air resistance, a projectile is launched from and returns to ground level. It follows a trajectory similar and has a range of 26 m. Suppose the launch speed is doubled, and the projectile is fired at the same angle above the grou..
A dipole is located at the origin, with charges +3 nC and -3 nCseparated by 4 μm. Consider a spherical Gaussian surfacecentered on the origin of radius 80 μm.

A singly charged ion of mass m is accelerated from rest by a potential difference ?V. It is then deflected by a uniform magnetic field (perpendicular to the ion's velocity) into a semicircle of radius R. What is the ratio of the masses of the ions
A 20 g ball is fired horizontally with initial speed v_0 toward a 110 g ball that is hanging motionless from a 1.10 m-long string. The balls undergo a head-on, perfectly elastic collision, after which the 110 g ball swings out to a maximum angle t..
