Homework Help: Can You check my answer please

  1. Jan 21, 2010 #1
    1. The problem statement, all variables and given/known data

    Determine the wavelength of the most intense electromagnetic radiation
    emitted from a furnace at 2500.1 °C.

    2. Relevant equations

    Wien Law Tλ max = 1/5 c2
    where c2= 1.44 cmK
    or another equation
    λ=b/T where B= 2.897*10^-3 m.k
    3. The attempt at a solution
    when I solve it with equation 1:
    I got 1.0388*10^-4 cm
    when I solve it with the second equation
    I got 1044.6 nm
    Please check my answer if it write if the equations are write to solve the problem and check my significant digits.

    Your answer(s) look good.
    When you do the calculation
    λ=c2 / 5T,​
    How many significant figures are there in c2? And in T?
