Answer:
A scientist is studying a shock wave from an earthquake, he is studying mechanical wave.
Explanation:
The shock waves are experienced during earthquake. At the area of increased pressure shock wave are created as the object in that places moves faster as compared to the speed of sound. Shock wave are type of mechanical wave. For its transfer it requires a medium. An electromagnetic wave can travel of its own without any medium, under electromagnetic wave gamma ray and radio wave comes. they are transverse wave.
- The wavelength range of Infrared radiation is 700 nanometers to 1 millimeter.
- The sun emits mainly near-infrared which is mainly composed of wavelength below 4 micrometers.
- The thermal range of infrared ranges between wavelengths 3.5 and 2.0 micrometers
Explanation:
The wavelength range of Infrared radiation is 700 nanometers to 1 millimeter. This also translates to a frequency range of 430 TeraHertz to 300 Giga Hertz.
Because the sun is a star and is hot in comparison to earth and other planetary bodies, the bigger range of infrared radiation it emits is in the near-infrared which is mainly composed of wavelength below 4 micrometers.
The earth's surface produces infrared radiation of the mid-infrared range while cooler substances will produce far-infrared range
The thermal range of infrared ranges between wavelengths 3.5 and 2.0 micrometers and is produced by black bodies.

Answer: Lewis dot structures aren't drawn for ionic compounds, such as MgCl2. Because there aren't any shared electron pairs in an ionic compound. Lewis structure are only drawn for molecular compounds, atoms, or some individual ions. If we want to visualize a chloride ion (Cl -), it's Lewis structure will show Cl with complete octet.
Explanation: Hope this helps you
