Dịch bài đọc:

Cầu vồng là một hiển thị quang học về màu sắc thường xuất hiện trên bầu trời khi một chùm ánh sáng mặt trời lọt qua hàng triệu giọt mưa. Mỗi màu riêng biệt từ quang phổ sẽ được gửi đến mắt bạn. Để điều này xảy ra, góc giữa tia sáng, giọt mưa và mắt người phải nằm trong khoảng từ 40 đến 42 độ.

 Sau khi nghiên cứu sâu về cầu vồng, Sir Isaac Newton đã có thể giải thích cách chúng được hình thành. Tuy nhiên, ông bị mù màu vì vậy ông phải dựa vào mắt trợ lý của mình, người có thể dễ dàng nhận ra tất cả bảy màu: đỏ, cam, vàng, xanh, xanh, chàm và tím. Trợ lý của ông cũng có thể nói rõ sự khác biệt giữa chàm và tím.

 Có hai loại cầu vồng. Cầu vồng chính là phổ biến nhất và có màu sắc đặc biệt nhất, với màu đỏ xuất hiện ở bên ngoài và màu tím bên trong. Cầu vồng thứ bất thường bởi vì ánh sáng được phản xạ hai lần trong giọt mưa trước khi nó tạo thành một cầu vồng, vì vậy màu sắc theo thứ tự ngược lại và không sáng như cầu vồng chính.

 Có một huyền thoại phổ biến rằng nếu bạn đến cuối một cầu vồng, bạn sẽ tìm thấy một nồi chứa vàng đang chờ bạn. Trên thực tế, không thể làm điều này, bởi vì một cầu vồng không có kết thúc - khi bạn đi đến chỗ mà cầu vồng dường như chạm đất, nó sẽ di chuyển ra xa nhanh như bạn đến gần.
