In glass, light travels with a speed of 2.0 × 10^8 m/s. light with a frequency of 3.6 × 10^14 hz moves through the glass. what is the wavelength of the light? a. 1.8 × 10^6 m b. 7.2 × 10^22 m c. 1.4 × 10^-23 m d. 5.6 × 10^-7 m

Wavelength= speed/ frequency
w= 2.0 × 10^8 m/s/  3.6 × 10^14 Hz
w=5.6 × 10^-7 m
The answer is D.5.6 × 10^-7 m

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then
