Challenge Problems
Push your limits with challenges.
Question 1
An object emits light with a wavelength of 500 nm, moving away from the observer at 240,000 km/s. Calculate the new observed wavelength.
💡 Hint: You need to convert km/s to m/s for the calculation.
Question 2
A star is exhibiting a red shift, resulting in a 4 nm change in wavelength. If its original wavelength was 600 nm, what is its observed wavelength?
💡 Hint: Remember red shift means increase in wavelength.
