...........(1)
Kinetic energy of other particle
............(2)
dividing equation (1)/(2)




Parallel light waves hit the surface of a still lake and reflect in the same direction and the interaction of light and matter that it illustrates is called regular reflection. Regular reflection occurs whenever the reflecting surface is very smooth. The surface of the still lake is smooth. I hope the answer helps you.
If you are charged to manage a project that aims to install wireless access points (aps) throughout the university campus, the steps to a foolproof plan for this project would be -
1. Recognize all of your network’s needs.
The most crucial step in any WiFi installation is probably knowing what your network needs are.
2. Select the appropriate hardware for your wireless network
Finding the ideal access point is much simpler if your needs are clear, but the wide range of options might be difficult.
3. Recognize your devices’ network restrictions.
It’s crucial to keep in mind that other factors besides your Internet connection and network hardware might affect how well your network performs.
4. Take into account the various cables you’ll need to use.
5. Consider how nearby interference may affect the installation of your wireless access point.
6. Decide where to put your wireless access point.
7. Analyze signal strength prior to making a decision.
