Use the following equations to solve the questions below

Wavelength, Frequency & Energy

c = 𝜆 x 𝜐 E = h x 𝜐

𝜆 = wavelength in meters

𝜐 = frequency in Hertz

c = 3 x 10⁸ m/sec (Speed of Light)

E = energy of a quantum (Joules (J))

h = Planck’s constant: 6.626 X 10 ^-34 J ·sec

Stefan-Boltzmann Law: M = σ T ⁴

M = Total energy emitted (watts/ m²)

σ = S-B constant, 5.67 x 10^-8 W m^-2 K^-4

T = Absolute temperature in K

Wien's Displacement Law: λm = A/T

λ_m = Wavelength of max radiation (m)

A = Constant, 2.9x10-³ m·K

T = Temperature (K)
