Transparent - when light is in context with transparent materials almost all of the the light is allowed to go through these materials.
Ex: glass
Translucent- materials that do not allow light to pass through easily.
Ex: tissue paper
Opaque- materials that allow no light to go through them .
Ex: wood
The emission wavelength of the atoms excited above the ground state is 599.8 nm.
<h3>Emission wavelength of the atoms</h3>
The emission wavelength of the atom is determined by using the following formulas as shown below;
E = hf
E = hc/λ
where;
- E is the energy of the atom
- h is Planck's constant
- c is speed of light
- λ is the emission wavelength
λ = hc/E
λ = (6.626 x 10⁻³⁴ x 3 x 10⁸) / (3.314 x 10⁻¹⁹)
λ = 5.998 x 10⁻⁷ m
λ = 599.8 x 10⁻⁹ m
λ = 599.8 nm
Thus, the emission wavelength of the atoms is 599.8 nm.

Answer:
For density you divide the mass by cm so for trail one the answer would be 34.31/1.64=20.9
Explanation:
The correct answer is C. Dr Smith, who measures 13.5 g/mL on e2020.
I think the correct answer from the choices listed above is option B. The list which includes three type of chemical reactions would be decomposition, single replacement, and double replacement. These are the most basic reactions in chemistry and are the basis for other types of reactions.
