Observation & Question

Physics concept(s) 

• • Nature of Light

  • Propagation of light

  • Refraction

  • Heat transfer

  • Photoelectric effect

Sustainability aspect(s) 

• • Renewable Energy Production

  • Energy Efficiency

  • Long-term Implications

  • Resource Conservation

Observation 

• • Surfaces that come into contact with a light source with stronger intensity gets hotter faster than a light source with less intensity

  • Increasing the frequency of light may result in more emission of more photoelectrons

Question 

• • How does frequency and intensity of light affect transfer in electricity?

  • How can we optimize LEDs for energy efficiency and resource conservation?
