Explain the phenomenon of dispersion by relating to Snell's Law. (A) This phenomenon is known as refraction. Snell's Law states that the ratio of the angles of incidence and refraction is equal to the inverse ratio of the indices of refraction. Refraction of light waves explains the dispersion of white light when it passes through a prism. (B) The change in direction of a wave at a boundary between two different media, so that the wave moves back into the medium it came from. (C) The conditions for total internal reflection are the the light is travelling from an optically denser medium (higher refractive index) to an optically less dense medium (lower refractive index) and that the angle of incidence is greater than the critical angle. (D) The angle of incidence in the denser medium must be greater than the critical angle for that pair of media. The ray of light must travel from a denser medium into a rarer medium.

A large sculpture of mass 2,400 kg was being transferred from the 3rd floor to the ground floor of the National Museum using a cable. It was uniformly decelerating for a height of 8 m until it reaches the ground floor. If the tension on the cable is 23,500 N, what is the initial speed of the sculpture as it is lowered down?

6. Son Ye Jin (SYJ), 45 kg, drops from a helicopter 4 km above the ground. Assume the air resistance is proportional to the velocity of the SYJ, with k 15 N-sec/m when the chute is closed and with constant k₂ = 105 N-sec/m when the chute is open.
