The peak wavelength for Betelgeuse is 828 nm
Explanation:
Wien's law describes how the surface temperature relates to a star’s peak wavelength:

where
represents the peak wavelength
T is the surface temperature
is Wien's constant
For Betelgeuse, the surface temperature is roughly
T = 3500 K
Consequently, its peak wavelength can be determined as:

Answer:
11.56066 m/s
Explanation:
m = Mass of individual
v = Velocity of individual = 13.4 m/s
g = Gravitational acceleration = 9.81 m/s²
v' = Velocity of the individual after dropping
At the surface, kinetic and potential energy will equalize

The cliff's height is 9.15188 m
Define fall height as h' = 2.34 m

The person's speed is 11.56066 m/s
Δd = 23 cm. When the eta string of the guitar has nodes at both ends, the resulting waves create a standing wave, which can be expressed with the following formulas: Fundamental: L = ½ λ, 1st harmonic: L = 2 ( λ / 2), 2nd harmonic: L = 3 ( λ / 2), Harmonic n: L = n λ / 2, where n is an integer. The rope's speed can be calculated using the formula v = λ f. This speed remains constant based on the tension and linear density of the rope. Now, let's determine the speed with the provided data: v = 0.69 × 196, yielding v = 135.24 m/s. Next, we will find the wavelengths for the two frequencies: λ₁ = v / f₁, which gives λ₁ = 135.24 / 233.08, equaling λ₁ = 0.58022 m; λ₂ = v / f₂ results in λ₂ = 135.24 / 246.94, consequently λ₂ = 0.54766 m. We'll substitute into the resonance equation Lₙ = n λ/2. At the third fret, m = 3, therefore L₃ = 3 × 0.58022 / 2, resulting in L₃ = 0.87033 m. For the fourth fret, m = 4, which gives L₄ = 4 × 0.54766 / 2, equating to L₄ = 1.09532 m. The distance between the two frets is Δd = L₄ – L₃, so Δd = 1.09532 - 0.87033, leading to Δd = 0.22499 m or 22.5 cm, rounded to 23 cm.
To address this problem, Boyle's Law must be applied, which states that the initial and final pressures and volumes are related as follows: Where, P₀ and V₀ represent the initial pressure and volume, while P and V refer to the final pressure and volume. The endpoint pressure in this scenario is atmospheric pressure. Thus, using the given equation, we can find the volume the lungs would occupy at the surface.
Answer:
The convergence of light rays redirects them toward the focal point, resulting in a magnifying effect.
