Light Waves and Their Properties

The video tutorial covers light wave interactions, focusing on absorption, reflection, and transmission. Students explore key concepts through activities and simulations, revisiting previous lessons to deepen understanding. The tutorial includes a reading activity on color perception and a homework assignment to reinforce learning.

What happens to light when it is not absorbed by an object?

• It becomes heat.

• It changes color.

• It is transmitted or reflected.

• It disappears.

According to Key Concept 11, what happens to light that is not transmitted or reflected?

• It loses energy.

• It becomes visible.

• It is absorbed.

• It changes direction.

What is the relationship between wavelength and frequency in light waves?

• Higher wavelength means lower frequency.

• Wavelength and frequency are unrelated.

• Lower wavelength means lower frequency.

• Higher wavelength means higher frequency.

What is the primary focus of the warm-up activity on light waves?

• Understanding light absorption.

• Examining amplitude, frequency, and wavelength.

• Learning about light reflection.

• Exploring light color changes.

In the simulation, what happens to energy when light is reflected off a material?

• The energy changes the material's color.

• The energy is reflected with the light.

• The energy is lost.

• The energy is absorbed by the material.

In the simulation, what is the goal when testing materials with green light?

• To find materials that absorb green light.

• To find materials that transmit and reflect green light.

• To change the color of green light.

• To measure the speed of green light.

What happens to the energy of light when it is transmitted through a material?

• The energy changes the material's color.

• The energy passes through with the light.

• The energy is absorbed by the material.

• The energy is lost.

Why does a black object get warm when visible light shines on it?

• It reflects all light.

• It absorbs all light.

• It transmits all light.

• It changes the light's color.

What is the effect of light waves traveling through different mediums like air and water?

• They become invisible.

• They travel at different speeds.

• They change color.

• They travel at the same speed.

How does the reading activity explain the appearance of a purple water bottle?

• It absorbs all colors except purple.

• It reflects all colors.

• It transmits purple light.

• It changes the color of light.
