Question

1. (1 point) When light passes from one medium into another (from air into water for example), which of the following properties of the light change? (Circle all that apply) A. The speed B. The frequency C. The wavelength o ob obali 2. (1 point) You and a friend are conducting a science experiment. Your friend takes 3 lasers to a distant hilltop: blue, green, and red. He carefully aims them onto a target next to you. He then turns all 3 lasers on at the exact same instant in time. Which of the following statements is true? A. The blue light arrives first, followed by green, and then red. B. The red light arrives first, followed by green, and then blue. C. The green light arrives first, then the blue and red lights arrive at the same time. D. The blue, green, and red lights all arrive at the same time.

1 & 2 please

Answer 1

The refractive index of medium is defined ol> where air C= velocity of light in velocity of light the medium, cam that say N= for v<c / that the we can see medium changes Also, the frequency the velocity changes does not change c=2a V= va Da cla </

the median It implies that wavelength Changes, changes. i velocity and wavelength changes. frequency does not change. All anive of at the them will time because same all thêm are electromagnetic wares (of different wavelengths) and they all travel with the &ame speed speed c (in air).
