Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.

Question

Two ships are moving along a line due east (Fig. P14.76). The trailing vessel has a speed relative to a land-based observation point of v₁ = 64.0 km/h, and the leading ship has a speed of v₂ = 45.0 km/h relative to that point. The two ships are in a region of the ocean where the current is moving uniformly due west at v_current = 10.0 km/h. The trailing ship transmits a sonar signal at a frequency of 1200.0 Hz through the water. What frequency is monitored by the leading ship?

A vibrator, pulley, and hanging object are arranged as in Figure P18.219(attachment) with a compound string, consisting of two strings of different masses and lengths fastened together end-to-end. The first string, which has a mass of 1.56 g and a length of 61.0 cm, runs from the vibrator to the junction of the two strings. The second string runs from the junction over the pulley to the suspended 7.02 kg object. The mass and length of the string from the junction to the pulley are, respectively, 6.75 g and 100.3 cm. a) Find the lowest frequency for which standing waves are observed in both strings, with a node at the junction. The standing wave patterns in the two strings may have different numbers of nodes. b) What is the total number of nodes observed along the compound string at this frequency, excluding the nodes at the vibrator and the pulley?
