Exploring Max Planck's Quantized Energy Concept

Who was the physicist that opened the door for 20th-century physics?

• Niels Bohr

• Isaac Newton

• Albert Einstein

• Max Planck

What does classical physics say about the relationship between energy and frequency?

• Energy and frequency are unrelated

• As frequency goes up, energy goes down

• As frequency goes down, energy goes up

• As frequency goes up, energy goes up
