Electromagnetic Waves and Their Properties

This video tutorial covers the basics of electromagnetic radiation, focusing on light calculations. It explains light as a wave, its speed, and different types of light, such as radio waves and gamma rays. The video discusses how light energy affects electron movement and molecular vibration. It also includes calculations involving wavelength, frequency, and energy, using Planck's constant.

What is the term used to describe the distance between two peaks in a wave?

• Amplitude

• Velocity

• Frequency

• Wavelength

Which type of electromagnetic wave has the highest energy?

• Microwaves

• Infrared

• Radio waves

• Gamma rays

What happens to electrons when they absorb ultraviolet light?

• They remain in the same energy level

• They move to a lower energy level

• They move to a higher energy level

• They are ejected from the atom

Which type of light has enough energy to vibrate molecules but not move electrons?

• Infrared

• Microwaves

• Ultraviolet

• Gamma rays

What is the speed of light in a vacuum?
