Chapter 1. Understanding Light

Peak Wavelength

Click on the peak wavelength for one of the three stars represented in this image. You must click on one of these peaks to receive credit.

BUT REMEMBER, the star is still emitting at other wavelengths.","type":"correct","color":"#99cc00","code":"[{\"shape\":\"circle\",\"coords\":\"70,70,19\"}]"} {"title":"peaks2","description":"The peak wavelength is the highest point on the curve.

Wien's Law

Using what you have learned about blackbody curves. Click on a portion of the image that shows the blackbody curve for the COOLEST object.

Three stars are pointed out in these images. Which stars has the lowest temperature?

Click on the correct answer to receive credit.

{"title":"coolest","description":"According to Wein's Law, the lower the temperature of a star, the longer the wavelength. Red light has a longer wavelength than orange or yellow.","type":"correct","color":"#000000","code":"[{\"shape\":\"rect\",\"coords\":\"2,6,158,180\"}]"}
