Question

infrared waves have many different applications. select the true statements.
near-infrared wave reflection can be used to monitor the health of plants.
satellites monitor earths surface temperatures by detecting heat carried by infrared waves.
infrared waves are used to see smoke and particles in the air.
infrared waves emitted from volcanoes can be used to identify volcanic gases.

Explanation:

• Near-infrared reflection is used in agriculture to assess plant health by measuring how plants reflect these waves, which correlates with their condition.
• All objects emit infrared radiation based on their temperature; satellites detect this to map Earth's surface temperatures.
• Infrared imaging can penetrate smoke and air particles, as these do not absorb infrared waves as strongly as visible light, allowing visualization through them.
• Volcanic gases emit distinct infrared signatures, which can be detected and analyzed to identify the type of gases released by volcanoes.

Answer:

A. Near-infrared wave reflection can be used to monitor the health of plants.
B. Satellites monitor Earth's surface temperatures by detecting heat carried by infrared waves.
C. Infrared waves are used to see smoke and particles in the air.
D. Infrared waves emitted from volcanoes can be used to identify volcanic gases.
