Choose the best answer to fill the blanks of the following passage. Some answers may be used more than once, some may not be used:(1) ____________ is a form of energy that travels through space as oscillating electric and magnetic fields or waves that are produced when charged particles move or vibrate relative to one another. This form of energy covers a broad spectrum from radio waves to gamma rays, known as the (2)_____________. A discrete packet of this energy is called a (3)______________, which can be described by the distance spanned by one wave, known as the (4)____________ (λ), and/or by the number of oscillations the wave makes per second, known as (5)____________ (ν). These two parameters of such a wave are related by the equation c=λν, where c is the (6)____________. The photon’s (7)______________ (E) can be calculated using the equation E=hν, where h is (8)______________.When atoms emit light only at certain colors, they produce a (9)_________________—a spectroscopic fingerprint unique to each element. Bohr explained this by postulating discrete (10)______________ around the nucleus; an electron (11)__________________ from a higher to a lower level emits a photon whose energy matches the level gap. This unusual phenomenon of energy (12)_________________ and it’s explanation in terms of wave mechanics became the foundation for the field of (13)________________________.
