     Can you prove that light is a wave? Light is an electromagnetic wave. If you try hard, you may make two laser beams to interfere with each other, just like other waves. In this case we see an interference pattern of constructive and distructive interference, or dark and light regions.  So light can destroy other light and create dark regions.

     What is frequency? What is the pitch of a sound? What is high pitch sound and a low pitch sound? If you know the answers for these questions 👆, it is time for you to learn about the Doppler effect The pitch of the sound of a moving train can rapidly change from high to low - let's find out why! https://drive.google.com/drive/folders/1vQesqSfDAOip-850rXd_XR-UF4Gkk8EZ?usp=sharing     See and/or download the lesson materials  https://drive.google.com/drive/folders/1vQesqSfDAOip-850rXd_XR-UF4Gkk8EZ?usp=sharing

                                     What is sound?      Let's learn more about sound and try these three experiments ! ^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^ 1. Prove that sound is just a vibration of air using a tuning fork and a plastic box with seeds 2. Simulate waves on your computer! Sound is a longitudinal wave Can you hear sound in outer space/ vacuum? Who is Hazza Al Mansoori ? 3 . What is the speed of sound ? Let's measure it! Download or see the presentation and the experiment videos from Google Drive https://drive.google.com/drive/folders/15FMYWq_BBwvFrHb5dBv63s7TSNvsJLx8?usp=sharing ^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^^-^-^-^      These people built a giant horn in a desert, so they can measure the speed of sound directly!
