What is the arrangement of the color in the visible light spectrum from low frequency to hig
frequency?
red, orange, yellow, blue, indigo, green, violet
red, yellow, green, orange, pink, white, purple
violet, indigo, blue, green, yellow, orange, red
red, orange, yellow, green, blue, indigo, violet

Red, Orange, Yellow, Green, Blue, Indigo, Violet

Explanation:

The frequencies of the colours are different and that is what determines what colors we see in order from low to high this are the frequencies:

Color

Red   430–480 THz

Orange   480–510 THz

Yellow  510–540 THz

Green  540–580 THz

Blue  580–610 THz

Indigo610–670 THz

Violet  670–750 THz

As you can see the lowest frequency is the red, and the highest frequency is the color violet, that is the visible spectrum that humans can see, everything below and above is invisible to the naked human eye.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
