Gentian violet is an antiseptic dye that has been in use since 1890. The name is due to its colour — it is not made from gentian or violet flowers. Gentian violet has antifungal and some antibacterial activity and has traditionally been used as a topical treatment for a variety of dermatological conditions.
Answer:
λ = 5.75 10⁻⁷ mm
Explanation:
This is a slit interference exercise, we analyze each wavelength separately
λ = 657 nm indicate that the third dark pattern
a sin θ = (m + ½) lam
a sin θ = (3 + ½) 657 10⁻⁹
a sin θ = 2299.5 10⁻⁹ nm
for the other wavelength in the same place we have m = 4 bright
a sin θ = m lam
we substitute
2299.5 10⁻⁹ = 4 λ
λ =
λ = 5.75 10⁻⁷ mm

A. What can happen to energy in a system is that <u>it can be </u><u>converted</u><u>.</u>
<h3>
What is the principle of conservation of energy?</h3>
The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.
The energy of a system can be converted from one form to another.
Thus, what can happen to energy in a system is that <u>it can be </u><u>converted</u><u>.</u>

Answer:
That's simply because any electromagnetic wave longer than a microwave is called a radio wave. Microwaves: Obviously used for cooking in microwave ovens, but also for transmitting information in radar equipment. Microwaves are like short-wavelength radio waves. Typical size: 15cm (the length of a pencil).
