Properties of light

Question 1

What is light?

Answer 1

Electromagnetic radiation that travels in electromagnetic waves

Question 2

If the wavelength of an electromagnetic wave is shorter, how does it affect the frequency and energy?

Answer 2

Higher frequency, more energy

Question 3

If the wavelength of an electromagnetic wave is longer, how does it affect the frequency and energy?

Answer 3

Lower frequency, less energy
