Understanding Light and Electromagnetic Waves

What are photons in the context of light?

• Waves that travel in a circular path

• Particles that travel in a straight path

• Waves that travel in a spiral path

• Particles that travel in a zigzag path

How are the electric and magnetic fields oriented in an electromagnetic wave?

• In the same direction as the light beam

• Opposite to each other

• Perpendicular to each other and the light beam

• Parallel to each other

What does it mean when the electric and magnetic fields are 'in phase'?

• They reach their maxima and minima at the same time

• They do not interact with each other

• They reach their maxima and minima at different times

• They cancel each other out completely

What is the wavelength of a light beam?

• The speed of the light beam

• The frequency of the light beam

• The time it takes for one oscillation

• The distance between two consecutive maxima or minima

How is the frequency of an electromagnetic wave defined?

• The number of oscillations per second

• The time it takes for one oscillation

• The speed of the light beam

• The distance between two consecutive maxima
