I WONDER - What Is Wave length?

The video tutorial explains the concepts of frequency and wavelength, defining frequency as the number of waves passing a point per second, measured in Hertz. It describes wavelength as the distance between identical points on consecutive waves. The relationship between speed, frequency, and wavelength is expressed by the formula: Speed = Frequency x Wavelength. An example of light waves is provided, highlighting their high frequencies in the terahertz range and their speed of approximately 299,792 km/s in a vacuum.

What is the unit of measurement for frequency?

• Watts

• Seconds

• Meters

• Hertz

Which of the following best describes wavelength?

• The distance between two identical points on consecutive waves

• The height of a wave

• The speed of a wave in a medium

• The number of waves passing a point per second

What is the formula that relates speed, frequency, and wavelength?

• Speed equals wavelength divided by frequency

• Speed equals wavelength minus frequency

• Speed equals frequency divided by wavelength

• Speed equals frequency times wavelength

In what range do light wave frequencies typically fall?

• Kilohertz

• Megahertz

• Gigahertz

• Terahertz

What is the approximate speed of light waves in a vacuum?

• 150,000 kilometers per second

• 299,792 kilometers per second

• 500,000 kilometers per second

• 1,000,000 kilometers per second
