- Please solve and answer the question correctly please. Be sure to give the correct units and answers. Thank you!!Student 1: The red light has a higher wavelength (A) than the blue light. Using the equation v = f* A, that shows that the red light has a larger velocity (v) as well. Student 2: But both kinds of light should be moving at the same speed, since they are both going through the same medium, space. I think the blue light needs to have a higher frequency than the red light, to make up for the red light's higher wavelength. Do you agree or disagree with either or both of the students? Explain your reasoning.5. A baseball is moving to the right with a speed of v. At four different positions people have radar guns pointed at the ball to measure a Doppler shift in frequency in order to determine the baseball's speed, as shown in the diagram at the right (Note: wave fronts are NOT drawn to scale). Rank the measured shift in frequency of the radar beam from lowest to highest based on the 3 position of the radar gun. 1<2 < 4 < 3 3 < 4 < 2 < 1 4 < 2 < 3 < 1 3 <1< 2<4 А. В. C. D.

- Please help me with this.Attached is question.Student 1: The red light has a higher wavelength (λ) than the blue light. Using the equation v = f * λ, that shows that the red light has a larger velocity (v) as well. Student 2: But both kinds of light should be moving at the same speed, since they are both going through the same medium, space. I think the blue light needs to have a higher frequency than the red light, to make up for the red light’s higher wavelength. Do you agree or disagree with either or both of the students?
