Module 4 Review Game 1

Which color is absorbed and which is reflected by the leaves of most plants?

• Blue and green are absorbed; red is reflected.
• Green and violet are reflected; red is absorbed.
• Red and violet are reflected; green is absorbed.
• Red and blue are absorbed; green is reflected.

Which statement best explains what is seen on the building in the front left side of this image?

• The sunlight changes direction when it strikes the buildings on the left, so the buildings up the street are visible.
• Sunlight passes through the buildings on the left to show the buildings behind them.
• Light bounces back from the buildings across the way at the same angle and intensity that the buildings received the light.
• The light waves from the sun are taken into the buildings on the left, so parts of them are hidden from view.

What is the best description of the constructive interference of light?

• A mechanical wave meets an electromagnetic wave.
• Two waves have displacement in opposite directions.
• A longitudinal wave meets a transverse light wave.
• Two waves have the same direction of displacement.

What causes a diffuse reflection?

• Light waves strike a smooth, polished surface at a 90 degree angle and are reflected back at a 45 degree angle.
• Parallel light waves strike a smooth, polished surface and reflect back in the same direction.
• Light waves strike a rough, uneven surface at a 45 degree angle and are reflected back at a 90 degree angle.
• Parallel light waves strike a rough, uneven surface and reflect in different directions.

Which statement is true about the part of the electromagnetic spectrum that human eyes can detect?

• It is divided into nine ranges of wavelengths.
• It contains ultraviolet, visible, and infrared light.
• It is divided into seven ranges of wavelengths.
• It contains only the colors of the rainbow and television waves.

What is produced when constantly changing electric and magnetic fields cause electrically charged particles to vibrate or accelerate?

• magnetic fields in space
• electromagnetic waves
• electromagnetic spectrum
• transverse magnetic waves

Which statement correctly compares radio waves and microwaves?

• Radio waves have longer wavelengths and higher frequencies than microwaves.
• Radio waves have longer wavelengths and lower frequencies than microwaves.
• Radio waves have shorter wavelengths and lower frequencies than microwaves.
• Radio waves have shorter wavelengths and higher frequencies than microwaves.

Which statement correctly compares infrared light to visible light?

• Infrared light has a lower frequency and longer wavelength than visible light.
• Infrared light has higher radiant energy but a shorter wavelength than visible light.
• Infrared light has a lower radiant energy and shorter wavelength than visible light.
• Infrared light has a higher frequency and longer wavelength than visible light.

What enables humans to "see" light in the infrared range of the electromagnetic spectrum?

• video camera
• thermogram
• UV sensor
• RFID chip

Most objects emit infrared energy. How do humans recognize this?

• They experience "goose bumps" on their skin.
• They see light emitted from the object.
• Their skin senses it as warmth.
• Their vision becomes clearer.
