Your Answer ▼ The passage proposes three conceivable theories what made will-o'-the-wisp occurs. However, the lecturer refutes that hypothesis are not convincing.
First of all, The passage urges that will-o'-the-wisp is caused by chemical illumination. The professer counters the idea that chemical produced by gas is not reasonable for the phenomenon. Though the gas initiates glows in the air, it shows cool and greenish color, while will-o'-the-wisp tends to be seen warm and yellow.
Moreover, the professor states that fireflies can not be the reason of the phenomenon. Although fireflies produce lights, their glowing is wide spreaded, unlike will-o'-the-wisp take places relatively in small area. To elaborate, she also explains that glowing of the fireflies is synchronized blinking, whereas will-o'-the-wisp does not.
Finally, the passage argues that reflection from barn owls' feather may explain the phenomenon. However, the lecturer disagrees with the argument, pointing out the feathers of the barn owls are not entirely white. Hence, if there is no consistense light, reflection would not look like a light of will-o'-the-wisp, which is usually floated in the air. |
