The surface temperature of the star Vega is 9.6 × 103 K, and the surface temperature of the star Betelgeuse is 3.6 × 103 K. Assuming both stars behave as ideal blackbody radiators with Wien's displacement constant 2.9 × 10-3 m K, which statement correctly identifies the regions of the electromagnetic spectrum containing their peak emission wavelengths?

Vega's peak emission is in the ultraviolet region; Betelgeuse's peak emission is in the infrared region.

Vega's peak emission is in the infrared region; Betelgeuse's peak emission is in the ultraviolet region.

Vega's peak emission is in the visible region; Betelgeuse's peak emission is in the ultraviolet region.

Vega's peak emission is in the ultraviolet region; Betelgeuse's peak emission is in the microwave region.
