1. A wave has a frequency of 3800 Hz and a wavelength of 0.50 m. What is its speed?
Light passes at an angle of 30.0 degrees to the normal from air (n=1.0003) into glass (n=1.50).
3. What is the angle of refraction?
4. A light wave has a wavelength of 680 nm. What is its frequency?
Please show the formulas used, work done and the answer. Thank you!
