The letter D because the more the N on the left have more on the right.
Answer:
E = 3.77×10⁻¹⁹ J
Explanation:
Given data:
Wavelength of absorption line = 527 nm (527×10⁻⁹m)
Energy of absorption line = ?
Solution:
Formula:
E = hc/λ
h = planck's constant = 6.63×10⁻³⁴ Js
c = speed of wave = 3×10⁸ m/s
by putting values,
E = 6.63×10⁻³⁴ Js × 3×10⁸ m/s / 527×10⁻⁹m
E = 19.89×10⁻²⁶ Jm /527×10⁻⁹m
E = 0.0377×10⁻¹⁷ J
E = 3.77×10⁻¹⁹ J

Answer:
Another name for light is ¨Electromagnetic Radiation, luminous energy, and/or radiant energy.¨
Explanation:
Light is the electromagnetic radiation that´s capable of causing a visual sensation and has wavelengths from about 380 to about 780 nanometres. Electromagnetic radiation includes Radio Waves, Microwaves <u>(used in microwaves)</u>, Infrared Radiation <u>(heat)</u>, Visible Light <u>(the colors we see)</u>, Ultraviolet <u>(the UV radiation that causes sunburns)</u>, X-Rays <u>(used in medical X-Rays)</u>, and Gamma Rays <u>(which can be used to treat cancer)</u>. Light waves are transverse waves because they only travel east or west, but their crests and troughs face north and south (if desplayed on a coordinate grid). They wouldn´t be longitudinal waves because these waves don´t have vertical crests and troughs.
I hope this helps!
