Can you please help me with these problems as much as you can? :(

1)

Calculate the wavelength of the photons with the given frequencies and determine the type of electromagnetic radiation for each combination. frequency: 3.00 X 1021 Hz t e frequency: 9.00 X 1012 Hz t e Enter numeric value frequency: 6.00 x 1015 Hz wavelength: type mThe speed of light c in a vacuum is 2.997 x 10 m/s. Given that the index of refraction in fresh water is 1.333, what is the speed of light fresh water in fresh water? Ufresh water = m/s Given that the index of refraction in diamond is 2.419, what is the speed of light Udiamond in diamond? U diamond = m/s
