1. The speed and the wavelength of a water wave in deep water are 18.0 cm/s and 2.0 cm, respectively. The speed in shallow water is 10.0 cm/s. Find the corresponding wavelength. 2. You are measuring the wavelength of light from a certain single-colour source. You direct the light through two slits with a separation of 0.15 mm, and an interference pattern is created on a screen 3.0 m away. You find the distance between the first and the eighth consecutive dark lines to be 14.0 cm. At what wavelength is your source radiating? Communication 1. An FM radio station broadcasts at a frequency of 2.3 x 10* Hz. Determine the wavelength of the FM radio waves from this station 2. Red light with a wavelength of 6.50 x 102nm travels from air into crown glass(n=1.52) a) What is its speed in glass? b) What is its wavelength in the glass
