Question

which is true about the way sunlight changes from winter to summer?
sunlight travels faster in summer.
sunlight is more intense in summer.
sunlight has higher wavelengths in summer.
sunlight has greater frequencies in summer.

Explanation:

In summer, the Earth's tilt and position in its orbit result in sunlight hitting the surface at a more direct angle, making it more intense. The speed of light is constant in a vacuum, so sunlight doesn't travel faster in summer. Wavelength and frequency of sunlight are determined by the Sun's radiation and don't change seasonally in a significant way related to the change from winter to summer.

Answer:

Sunlight is more intense in summer.
