Question

A Yellow Giant is a luminous giant star of approximately 85 times brighter than the surface of the Earth’s Sun. The color is Orange and have a surface temperature of 5400 K. True or false? Answer Fast Please.

Answer 1

the statement is FALSE

Step-by-step explanation:

To answer this question we use that thermodynamic energy is

E = K T

also according to the Planck relation

E = h f

the speed of light et related to frequencies and wavelength

c = λ f

f = c /λ

we substitute

hc /λ = KT

λ= hc / k T

calculate us

lam = 6.62 10⁻³⁴ 3 10⁸ / 1.381 10⁻²³ 5400

lam = 2,663 10⁻⁸ m

let's reduce to num

lam = 2,663 10

lam = 26,63 nm

This wavelength is in the farultraviolet, therefore the statement is FALSE
