Answer:
Wavelength of light in diamond λ2 = 179.75 nm (Approx.)
Explanation:
Given:
Blue light of wavelength λ1 = 435 nm
n2 in diamond = 2.42
Find:
Wavelength of light in diamond λ2
Computation:
Since the wavelength is smaller, the frequency stays constant. The frequency of vibrations does not shift when they pass from one source to the next.
So,
n1λ1 = n2λ2
(1)(435) = (2.42)λ2
Wavelength of light in diamond λ2 = 179.75 nm (Approx.)
Answer:
Number of neautrons
Explanation:
Atoms from two different elements may have the same number of neutrons, but never the same number of protons. The number of protons is unique to the element and represents the atomic number. (sorcastic.org)
Answer:
V₁/5
Explanation:
The charge stored in the capacitor of capacitance, C and voltage V is Q = C₁V₁. If the voltage is removed and mica with dielectric constant k = 5 is inserted, the charge stored Q = C₂V₂. Since the charge stored is the same,
C₁V₁ = C₂V₂ ⇒ V₂ = C₁V₁/C₂. Now C₂ = kC₁ ⇒ C₁/C₂ = 1/k = 1/5
So, V₂ = C₁V₁/C₂ = V₁/5
