The video tutorial explores the properties of waves, including amplitude, wavelength, and frequency. It explains how sound waves require matter to travel, while light waves do not. The tutorial demonstrates wave interactions such as reflection, absorption, and transmission, using examples like ghost crystals and lasers. It also covers practical applications of these concepts in everyday life, such as in glasses, solar panels, and cameras.

What does the frequency of a wave measure?

• The height of the wave

• How many waves pass a point in one second

• The speed of the wave

• The distance between waves

What is the unit of frequency?

• Meters

• Hertz

• Nanometers

• Decibels

How does amplitude affect the brightness of light?

• Changes the color instead

• Higher amplitude makes it brighter

• No effect

• Higher amplitude makes it dimmer
