What is the wavelength of a 3*10^12 hz infrared wave a 3*10^20m b 1* 10^4m c 3*10^-3m d 1*10^-4 m

D. 1 × 10⁻⁴ m

Explanation:

Electromagnetic waves travel through space with the speed of light which is approximately 3.0 ×10⁻⁸ m/s.

The speed is calculated as follows:

c=λf

Where λ is the wavelength of the wave, f the frequency and c the speed of light.

Thus λ=c/f

=(3×10⁸ m/s) / (3×10¹²Hz)

Wavelength, λ= 1 × 10⁻⁴ m

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
