D. the reflection of each concave lens makes the object appear larger
<em>The frequency of the wave with a wavelength of is</em> <u>3.748 × 10 ⁶ /s</u>.
I attached the working and the answer to the question below. I hope I was able to help.
Please note that C = speed of light (2.998 × 10⁸ m/s), ν = frequency and λ= wavelength.
Answer:16.38085
Explanation:Aline the decimals then start multiplying.
Limestone is easily weathered by acid rain. When rain mixes with gases such as sulfur dioxide and carbon dioxide in the atmosphere, acid rain is formed (sulfuric acid and carbonic acid respectively). When the rain precipitates and meets with limestone which is CaCO3, it is weathered a shown by the formulae; 2CaCO₃ (s) + H₂CO₃ → 2CaHCO3 (aq)
Geographical features formed as a result of weathering of limestone in rocks are caves, stalactites, and stalagmites.
