The table displays the velocity of light in three different states of matter.
Material | Speed (meters/second)
air | 300,000,000
water | 220,000,000
glass | 200,000,000
When would the speed of light decrease? (1 point)
A. When light transitions from glass to air. B. When light moves from glass to water.
C. When light moves from air into water. D. When light transitions from water to air.
C. When light moves from air into water.
I'm just gonna type in all of the answers since I failed cus of questions llc. Here they are.
1: "20 cm"
2: "Z"
3: "Yes/Yes/No/Yes/No/Yes"
4: "Does the wave require a medium to travel?"
5: "An X ray wave exhibits a frequency greater than that of an infrared wave"
6: "Gamma ray"
7:"Voilet,Indigo,Blue,Green,Yellow,Orange,Red"
8: "The greater energy of X-rays is reflected in their shorter wavelength"
9: "Gamma waves are employed in medicine to reduce problematic cells in size"
10: "their short wavelengths"
11: "The elevated energy level of X-rays enables them to penetrate through the human body"
12: "visible waves"
13: "absorbing different wavelengths of light"
14: "To explain that light travels in a straight line UNTIL it transforms from one material to another"
15: "the ponds water reflects sunlight, creating a mirrored image"
16: "As light crosses the boundary between air and water, it undergoes refraction.
17: "When light moves from air to water"
18: "Copper"
19: (The one that goes slanted down, then straight down, then slanted again)
20: "Light waves travel faster in air than in solids"
21: "She increases the frequency of the wave"
22: "Wave 3, 2, 1"
23: "Wave X has LESS energy than Z"
24: "the longer the wavelength, the lower the frequency"
25: "The lens refracts light inward, generating a virtual image"
26: "The student should illustrate the light entering the lens and then departing in lines that are spreading out"
27: (the one going down)
28: (the one that's in a zigzag pattern)
Anyways, this is for Lessons 15 "Waves Unit Test" on connexus
