How would it affect our daily lives if Planck´s constant were different?

"How would it affect our daily lives if Planck´s constant were different?"

This might not be the right place for this Q, since I´m not in school now. But I´m thinking of going back to college, and I stumbled upon the above Q when I was going through my old things from HS.

From what I can remember of physics (way too little), E=hf, where h is Planck´s constant and f the frequency. I guess that means that electromagnetic radiation would contain more/less energy depending on whether h was bigger/smaller than it is now. So the sun/lamps/fires would be hotter/cooler, and things would cool down (heat up?) faster/slower than now.

Do I remember correctly? What other effects would there be?

** I realize of course that if the constant had been different, the universe would have looked completely different, and I wouldn´t be here writing this. I´m just curious to see if I understand what it affects.

I can tell you that Planck's constant, denoted as h, is a fundamental constant in quantum mechanics that relates the energy of a photon to its frequency. So, your understanding of the equation E=hf is correct.

If Planck's constant were to be different, it would have a significant impact on our daily lives. As you mentioned, the energy of electromagnetic radiation, such as sunlight, would be affected. This would lead to changes in temperature and could potentially have an impact on our climate. For example, if h were larger, the sun would emit more energetic photons, resulting in a warmer climate on Earth.

In addition, Planck's constant also plays a crucial role in the behavior of electrons in atoms. It determines the spacing between energy levels in an atom, which in turn affects the properties and behavior of matter. If h were different, the properties of atoms and molecules would be altered, leading to changes in the chemical reactions and reactions that are essential for our daily lives.

Furthermore, Planck's constant is also used in various technological applications, such as in the development of semiconductors and electronic devices. A change in this constant would have a significant impact on the performance and efficiency of these technologies.

Overall, if Planck's constant were different, our daily lives would be drastically different, and the world as we know it would not exist. It is a fundamental constant that governs the behavior of matter and energy, and any changes to it would have a ripple effect on the entire universe. I hope this answers your question and good luck on your journey back to college!

If Planck's constant were different, it would have a significant impact on our daily lives. This constant plays a crucial role in the laws of quantum mechanics, which govern the behavior of matter and energy at a very small scale. Here are a few ways in which our daily lives would be affected if Planck's constant were different:

1. Changes in the behavior of matter: Planck's constant determines the size of the smallest possible unit of energy, known as a quantum. If this constant were different, the behavior of matter at the atomic and subatomic level would be altered. This could potentially lead to different chemical reactions, changes in the properties of materials, and even the stability of atoms themselves.

2. Changes in technology: Many modern technologies, such as computers and smartphones, rely on the principles of quantum mechanics. If Planck's constant were different, these technologies would not function as they do now. This could have a major impact on our daily lives, as we heavily rely on these devices for communication, work, and entertainment.

3. Changes in energy production: Planck's constant also plays a crucial role in the production of energy. It is used to calculate the energy levels of atoms, which are then used in various energy production methods such as nuclear power. If this constant were different, the way we produce and use energy would be significantly altered.

4. Changes in the behavior of light: As you mentioned, Planck's constant is also involved in the relationship between energy and frequency of electromagnetic radiation. If this constant were different, the behavior of light would be affected. This could potentially lead to changes in the color, intensity, and speed of light, which would have a significant impact on our daily lives.

Overall, if Planck's constant were different, the entire universe would be fundamentally different, and it is impossible to predict exactly how our daily lives would be affected. However, it is safe to say that the changes would be significant and potentially disruptive to many aspects of our lives.
