1) From the law of reflection of light, it can be known that the incident ray, the reflected ray and the normal are in the same plane, according to the angle between the incident ray and the reflected ray, the normal is made through the reflection point, and then the perpendicular line of the law line is the mirror surface, as shown in the figure >>>More
The magnitude of the angle of incidence i is 60°
The angle of reflection is also 60° >>>More
The stool is unlucky, the landlord's wallet is full and washed is to wash away the bad luck, with a bamboo pole to explain the high festival, indicating that the landlord is going to have financial luck recently.
You don't have to think too complicated, it's just a dream, the dream is very casual, just laugh it off. Happy to you!
There's no way, I fell into the track, ask the conductor to stop and look for it, if you go down to look for it, you won't be able to get on the train, and it's impossible to wait for you with a car. Let's weigh the bigger loss.
