] The diagram below plots the wavelength and relative brightness of stars at different temperatures.

The image shows four blackbody curves, plotting the wavelength and relative brightness of stars at various temperatures. The x-axis represents the wavelength in nanometers and the y-axis represents relative brightness. There is a band of color represented as part of the graph vertically, purple, blue, light blue, green, yellow, orange and red from left to right. Curve 1 peaks at a wavelength of 600nm, Curve 2 peaks at a wavelength of ~480 nm, Curve 3 peaks at a wavelength of 500 nm and Curve 4 peaks at a wavelength of 350nm.

Which curve best represents a blue star?

Curve 1
Curve 2
Curve 3
Curve 4
