Question

while the human eye cannot see infrared waves, we feel infrared waves as heat. a burning fire emits both visible light and infrared waves. when the radiant energy carried by infrared waves strikes an object, it is converted into heat, or thermal energy. so when you warm your hands beside a campfire, the energy carried by infrared waves travels from the fire to your hands and warms them up. select the true statements. energy is transferred from the fire to your hands by infrared waves. thermal energy is converted to radiant energy when infrared waves strike an object. a fire gives off both infrared waves and visible light. infrared waves are visible to the human eye.

Explanation:

1. The text states "the energy carried by infrared waves travels from the fire to your hands and warms them up", so energy is transferred from the fire to hands by infrared waves.
2. It says "When the radiant energy carried by infrared waves strikes an object, it is converted into heat, or thermal energy", not thermal to radiant.
3. "A burning fire emits both visible light and infrared waves" is clearly mentioned.
4. "While the human eye cannot see infrared waves" is given in the text.

Answer:

• Energy is transferred from the fire to your hands by infrared waves.
• A fire gives off both infrared waves and visible light.
