Reading: Visible Light and Its Properties

What is the range of wavelengths for visible light that the human eye can perceive?

• 380 to 700 nanometers

• 300 to 800 nanometers

• 400 to 750 nanometers

• 350 to 720 nanometers

What happens when light waves strike an object and are absorbed?

• The energy is converted into heat

• The light is reflected

• The light is transmitted

• The light is refracted

Why do we see certain colors when light interacts with objects?

• Because the light that is reflected or transmitted to our eyes determines the color

• Because all colors are absorbed and none are reflected

• Because the object emits its own light

• Because the object's natural frequency matches all light frequencies

What is the speed of light in a vacuum?

• Approximately 299,792,458 meters per second

• Approximately 300,000,000 meters per second

• Approximately 150,000,000 meters per second

• Approximately 299,000,000 meters per second

What is the principle behind additive color mixing?

• Combining different colors of light to create new colors

• Absorbing all colors and reflecting none

• Reflecting only one color and absorbing others

• Transmitting all colors through an object
