This shows why sound travels faster in solids, slower in liquids, and slowest in gases

REFLECTION "My parents were married for 55 years. One morning, my mom was going downstairs to make dad breakfast, she had a heart attack and fell. My father picked her up as best he could and almost dragged her into the truck. At full speed , without respecting traffic lights, he drove her to the hospital. When he arrived, unfortunately she was no longer with us. During the funeral, my father did not speak; his gaze was lost. He hardly cried. That night, his children joined him. In an atmosphere of pain and nostalgia, we remembered beautiful anecdotes and he asked my brother, a theologian, to tell him where Mom would be at that moment. My brother began to talk about life after death, and guesses as to how and where she would be. My father listened carefully. Suddenly he asked us to take him to the cemetery. Dad!" we replied, "it's 11 at night, we can't go to the cemetery right now!" He raised his voice, and with a glazed look he said: "Don't argue with me, please don't argue with the man who just lost his wife of 55 years." There was a moment of respectful silence, we didn't argue anymore. We went to the cemetery, we asked the night watchman for permission. With a flashlight we reached the tomb. My father caressed her, prayed and told his children, who watched the scene moved: "It was 55 years... you know? No one can talk about true love if they have no idea what it's like to share life with a woman." He paused and wiped his face. "She and I, we were together in that crisis. I changed jobs ..." he continued. "We packed up when we sold the house and moved out of town. We shared the joy of seeing our children finish their careers, we mourned the departure of loved ones side by side, we prayed together in the waiting room of some hospitals, we support each other in pain, we hug each Christmas, and we forgive our mistakes... Children, now it's gone, and I'm happy, do you know why? Because she left before me. She didn't have to go through the agony and pain of burying me, of being left alone after my departure. I will be the one to go through that, and I thank God. I love her so much that I wouldn't have liked her to suffer..." When my father finished speaking, my brothers and I had tears streaming down our faces. We hugged him, and he comforted us, "It's okay, we can go home, it's been a good day." That night I understood what true love is; It is far from romanticism, it does not have much to do with eroticism, or with sex, rather it is linked to work, to complement, to care and, above all, to the true love that two really committed people profess ".

Propagation speed of sound in steel, water and air 🛂 Higgsino physics library — YouTube

The speed of light is around 300,000,000 m/s. To put this into perspective, it takes 8 minutes and 20 seconds for light to travel from the sun to Earth, a whopping distance of 148 million kilometres!

Same:

So an intersting question: What If a plane flies faster than the speed of sound Sound is a compression wave that travels through air. Given a certain air temperature, the sound will travel at different speeds through the air. If a plane flies faster than the speed of sound means that the compression waves it is generating will remain behind the aircraft. As you can see on the right picture, if the aircraft is travelling faster that the speed of sound, the compression waves it generated in the past will remain behind. If it would stop/slow down, the waves would then catch up with the plane and a person on board would be theoretically capable of hearing them.

The speed of sound varies depending on the medium through which it travels. In dry air at sea level and at a temperature of 20 degrees Celsius (68 degrees Fahrenheit), the speed of sound is approximately 343 meters per second (1,125 feet per second). This speed can change with variations in temperature, humidity, and the composition of the medium through which sound waves propagate. In general, sound travels faster through denser materials.

Wow Visualizing this is very powerful That's soooo fast nehnn. The average speed of sound in air is 343.2 metres per second The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. The speed of sound is 343.2 metres per second. The table shows how fast sound travel via different media
