Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
Expert Solution & Answer
To determine
To explain: Speed of light in air and water.
Explanation of Solution
As light passes from air to water, it changes from one medium to another. In terms of refractive index, water is denser than air.
Hence, the wave speed of light decreases in water. Therefore, some light waves undergo refraction, while some of them reflect back from the plane of water.
Conclusion:
Hence, the speed of light in air and water is described.

2. Consider the situation described in problem 1 where light emerges horizontally from ground level.
Take k = 0.0020 m' and no = 1.0001 and find at which horizontal distance, x, the ray reaches a height
of y = 1.5 m.
2-3. Consider the situation of the reflection of a pulse at the interface of two string described in the previous problem. In addition to the net disturbances being equal at the junction, the slope of the net
disturbances must also be equal at the junction at all times. Given that p1 = 4.0 g/m, H2 = 9.0 g/m
and Aj = 0.50 cm find 2. A, (Answer: -0.10 cm) and 3. Ay. (Answer: 0.40 cm)please I need to show all work step by step problems 2 and 3
From number 2 and 3 I just want to show all problems step by step please do not short cut look for formula
