Hope the below helps!
Explanation:
Greenhouse gases (such as methane, carbon dioxide etc) have lots of vibrating particles. These molecules eventually release radiation, which travels up Earth's atmosphere (because warm air rises), is trapped and adds to the greenhouse gas effect.
Oxygen and nitrogen don't interfere with infrared waves in the atmosphere. That's because molecules are picky about the range of wavelengths that they interact with.
I have attached a diagram that shows the greenhouse effect. It might help to visualise this.
The answer is Condenser. It is a small non non-magnifying
lens system that condenses light before it passes through the specimen.
Concentrates light on the specimen. Located beneath the stage. First, the iris
diaphragm creates an aperture that regulates the amount of light passing
through the condenser and ultimately the ocular lenses.
