Answer:
Red line is reflected ray.
Explanation:
According to the given figure, the blue line represent the incident ray. It strikes the surface and reflection occurs. The dotted line shows normal.
After reflecting the surface, the ray of light is reflected. Red line shows the reflected light.
In this case, the laws of reflection follows i.e. the angle of incidence is equal to the angle of reflection.
If an airplane is flying at 300 km/h to the east and is facing a headwind of 18.0 km/h, the final velocity can be calculated using simple vector addition. In this case, the planes velocity is positive (+330 km/h) and head wind has a negative component (-18.0 km/h). Vector addition yields +330 km / h + (-18.0 km /h) = 312 km / h.
Answer:
resistance of the metal conductor at different temperature
Explanation:
Alike - both part of the light spectrum, cannot be seen with the naked eye
Different - IR is less energetic than UV, UV has a shorter wavelength than IR
IR - infrared
UV - ultraviolet
