Determine the wavelength of light emitted or absorbed by a hydrogen atom when an electron transitions from n=3 to n=6. Give your answer in units of nm.
I got -109nm as my answer am i correct?
Wavelength problem help (Chemistry)!?

Rydberg equation :
1/λ = R [(1/n₁²) - (1/n₂²)]
where,
λ is the wavelength of light emitted (negative) or absorbed (positive)
Rydberg constant, R = 1.097 × 10⁷ /m
Initial energy level, n₁ = 3
Final energy level, n₂ = 6
Then,
1/λ = (1.097 × 10⁷) × [(1/3²) - (1/6²)] /m
λ = 1 / {(1.097 × 10⁷) × [(1/9) - (1/36)] m
λ = 1.09 × 10⁻⁶ m
λ = 1090 × 10⁻⁹ m
λ = 1090 nm
(The positive value indicates that the light absorbed.)
Wavelength of the light absorbed = 1090 nm
1/λ = R [(1/n₁²) - (1/n₂²)]

your answer is incorrect. you keep asking these same questions. Show your work and I'll help you out.
I give you plenty of examples in your previous equations.
