Question

A white light shines on a magenta filter. A red T-shirt and a green T-shirt are placed on the

opposite side of the filter and remain there for one hour. How will the temperatures of the two

T-shirts change and compare after one hour? Explain your reasoning.

Answer 1

the red flannel heats up and the green flannel remains at the same temperature.

Step-by-step explanation:

A magenta filter lets the red and blue colors through, absorbing the green color.

When these colors affect the flannels, the red flannel absorbs the red color and heats up.

the green flannel cannot absorb its color as it is blocked by the magenta filter, consequently it remains at the same temperature.

In short, the red flannel heats up and the green flannel remains at the same temperature.

When the flannels are placed in front of the filter, the two flannels get hot since the white one has all the colors.
