Question 23 2 pts Radiation with a 6.90 um wavelength is within the infrared range. What is its frequency? Please give your answer in THz (1 THz = 1012 Hz) and remember that electromagnetic waves travel at the speed of light, so vw = c = 3.00 x 108 m.s-1. Question 24 2 pts Radio waves transmitted through space at 3.00 x 108 m.s" by an alien spacecraft in a far-away galaxy have a wavelength of 0.058 m. What is their frequency in GHz (1 GHz = 109 Hz)? Question 25 2 pts What is the wavelength of the waves you create in a swimming pool if you splash your hand at a rate of 2.0 Hz and the waves propagate at 0.67 m/s
