Pick the wrong answer in the context with rainbow.a)When the light ray...
Explanation:
Observer Position:
An observer can see a rainbow when his back is towards the sun, not when his front is towards the sun. This is because rainbows are formed when sunlight is refracted, reflected, and dispersed in water droplets in the atmosphere. The observer needs to have the sunlight at their back to see the rainbow in front of them.
Formation of Rainbow:
- When sunlight enters a water droplet, it undergoes dispersion, where different colors of light are separated due to their different wavelengths.
- The light rays are then internally reflected inside the droplet and finally refracted as they exit the droplet.
- A primary rainbow is formed by one internal reflection, while a secondary rainbow is formed by two internal reflections.
- The order of colors in the primary rainbow is red, orange, yellow, green, blue, indigo, and violet, while in the secondary rainbow, the order is reversed.
Correct Answer:
Option C is the wrong answer because an observer can see a rainbow when their back is towards the sun, not when their front is towards the sun. This positioning is crucial for the sunlight to be refracted and reflected in the water droplets to form a rainbow.
By understanding the correct positioning of the observer and the formation of rainbows, we can appreciate the natural phenomenon better and explain it accurately in scientific terms.
Pick the wrong answer in the context with rainbow.a)When the light ray...
Yes because the sun should be behind the observer to see the rainbow
