True or False: Our eyes perceive only a narrow part of the electromagnetic spectrum.

Explanation:
Vision is limited to a small slice of the electromagnetic spectrum—the visible range. Our eyes detect light roughly from 380 to 750 nanometers, using rods and cones tuned to those wavelengths. Outside this narrow band, photoreceptors don’t respond, so we don’t see those wavelengths with unaided eyes. The universe emits across the entire spectrum, from radio waves to gamma rays, but we rely on specialized instruments to observe wavelengths beyond visible light. Therefore, the statement is true.
