An AM radio station uses radio waves with wavelengths of 300 meters. How much energy is in this wave? 1.7 x 10-24 J

E = 6.6×10⁻²⁸ J

Explanation:

Given data:

Wavelength = 300 m

Energy of wave = ?

Solution:

Formula:

E = h c/λ

c = 3×10⁸ m/s

h = 6.63×10⁻³⁴ Js

Now we will put the values in formula.

E = 6.63×10⁻³⁴ Js × 3×10⁸ m/s / 300 m

E = 19.89×10⁻²⁶ J.m / 300 m

E = 0.066×10⁻²⁶ J

E = 6.6×10⁻²⁸ J

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
