- Waves are capable of bending around obstacles. This effect is called diffraction.
- Light consists of electric and magnetic fields and behaves as a wave. Thus light is capable of bending around obstacles.
- Diffraction is noticeable when the order of size of the obstacle and size of the wavelength match.

- 2. Two loudspeakers in a 20 °C room emit 686 Hz sound waves along the x-axis. What is the smallest distance between the speakers for which the interference of the sound waves for a point on the axis is destructive?8. A 26m wavelength of a radio wave is produced by two sources simultaneously. The interference of these two waves are observed at a point on a line perpendicular to the source. The sources are at a distance 78 and 143m away from the point of observation. Describe the nature of interference at the point and also find the order of the max/min reception at that point.On the night of April 18, 1775, a signal was to be sent from the steeple of Old North Church in Boston to Paul Revere, who was 1.90 miles away : "One if by land, two if by sea." At what minimum separation did the sexton have to set the lanterns for Revere to receive the correct message about the approaching British? Assume that the patriot's pupils had a diameter of 4.00 mm at night and that the lantern light had a predominant wavelength of 600 nm. m
