Explanation:

Wavelength is the length traversed by the wave when it moves by an angle of 2*π that is 360 degrees . Here the two particles are (790-70) =720 degrees apart that is equal to 4*π or 2*360. So the wavelength is half of the length i.e. 0.5metre .

Scorpions

Scorpions look like tiny lobsters in front. In back, they have a long tail with a stinger at the end. It curls up and over their bodies. They have 8 legs, like spiders.

Venom: The stinger has venom. The venom causes pain and other symptoms when it is shot into the skin.

Size: average size is 3 inches (7.5 cm). Range in size from 1 - 7 inches (2.5 to 18 cm).

Scorpions are most active at night. They like dark and moist places.

There are about 40 types of scorpions in the US.

All scorpions can sting, causing pain, tingling, and numbness at the sting site. Note: Some stings do not inject venom.

The only US scorpion that can cause serious symptoms is the bark scorpion. See below.

Children and older adults are more likely to have severe symptoms. People with chronic medical problems are also at higher risk.
