Answer:</h3>
4.227 × 10^-19 Joules
<h3>
Explanation:</h3>
Energy of a photon of light is calculated by the formula;
E = hf, where h is the plank's constant, 6.626 × 10^-34 J-s and f is the frequency.
But, f = c/λ
Where, c is the speed of light (2.998 × 10⁸ m/s), and λ is the wavelength.
Given the wavelength is 470 nm or 4.7 × 10^-7 m
Therefore;
E = hc/λ
= (6.626 × 10^-34 J-s × 2.998 × 10^8 m/s) ÷ 4.7 × 10^-7 m
= 4.227 × 10^-19 Joules
Therefore, the energy of a photon with 470 nm is 4.227 × 10^-19 Joules
Based on exposure time and place, the Sun's radiation may have harmful or beneficial effects.
<h3>What is solar radiation?</h3>
Solar radiation refers to the radiation from the Sun in the form heat, light and other forms of radiation.
The radiation from the Sun may have harmful or beneficial effects.
The effects of the Sun's radiation can be classified as BE, HE or SP as follows:
- BE- UV rays can help treat some health conditions. It creates Vitamin D
- SP- Use sunblock lotion with SPF 15 during hot days.
- BE- With the presence of sunlight, farmers can dry their crops.
- HE- UV rays can damage the tissue in your eyes.
- BE- Research says that sunlight helps moods.
- HE- Too much exposure from the sun can cause skin cancer.
- SP- Use sunglasses when you stay under the sun.
- SP- Wear a wide- brimmed hat on sunny days.
- BE- Humans can do recreational activities on a sunny day.
- SP- Wear sunglasses that filter UV light.
- HE- Prolonged exposure to the sun’s heat makes your skin age faster than normal.
- HE- Too much heat from the sun can cause heat stroke and loss of water.
- BE- Sunlight helps strengthen your immune system.
- BE- The vitamin D made thanks to the sun plays a big role in bone health.
- SP- Avoid sun in the middle of the day, from about 10 a.m. to 3 p.m.

The assertion is definitely wrong. Corrosion actually means decomposing or rusting of metals. So, corrosion is a harmful process for metals. But, your reason is correct. Galvanising, which means deposition of a layer of zinc on iron to prevent from rusting, is a very beneficial process to prevent metals from corrosion. In some cases, electroplating also helps to prevent from corrosion.
