Answer:
C) Both wavelengths fall into the visible light region, but blue light has a smaller wavelength and higher energy than red light.
Step-by-step explanation:
The energy (E) of a wave is inversely proportional to its wavelength (λ).
E = (hc)/λ
E₁λ₁ = E₂λ₂ Divide both sides by λ₂
E₂ = E₁ × λ₁/λ₂
Let λ₁ refer to red light and λ₂ refer to blue light.
The wavelength of red light (λ₁ ≈ 800 nm) is greater than that of blue light (λ₂ ≈ 400 nm).
E₂ ≈ E₁ × (800/400)
E₂ ≈ 2E₁
E₂ > E₁
Blue light has more energy than red light.
A) is wrong. Red light has a longer wavelength than blue light.
B) is wrong. The order of wavelengths is IR > Red > Blue >UV. UV light has a shorter wavelength and greater energy than infrared light.
D) is wrong. UV waves are much shorter than UV waves.
Both wavelengths are fall into visible light region but blue light has a smaller wavelength and higher energy than red light.
