Consider the following wavelengths: (A) 0.94 m (B) 1.14 m (C) 1.40 m (D) 1.88 m
Water vapors absorb strongly at which of the above wavelengths?

Correct option is D

Explanation:
Water vapor is known to absorb infrared radiation across a range of wavelengths, particularly in the region between 0.7 µm and 1.88 µm. Each of the wavelengths listed has absorption characteristics due to water vapor:
1. 0.94 m (940 nm): Water vapor shows significant absorption at this wavelength, which is important for remote sensing applications.
2. 1.14 m (1140 nm): This wavelength also corresponds to a region where water vapor has a strong absorption band.
3. 1.40 m (1400 nm): This wavelength is well within the absorption bands of water vapor, indicating strong absorption characteristics.
4. 1.88 m (1880 nm): Similar to the other wavelengths, this too shows a significant absorption by water vapor.
Thus, since all four wavelengths exhibit notable absorption by water vapor, option (d) is indeed correct.
Information Booster:
· Infrared Absorption: Water vapor has distinct absorption features that play a crucial role in atmospheric science.
· Importance in Climate Studies: The absorption properties of water vapor are fundamental for understanding the greenhouse effect and climate change.
· Measurement Techniques: Many remote sensing technologies utilize these absorption characteristics to estimate atmospheric humidity and temperature profiles.
· Applications: Knowledge of water vapor absorption is applied in meteorology, hydrology, and environmental monitoring.
Additional Information:
· Option (a) incorrectly states that only (a), (b), and (c) have significant absorption.
· Option (b) excludes the 0.94 m wavelength, which does show absorption by water vapor.
· Option (c) similarly excludes 1.14 m and is therefore incorrect.
