The portion of the visible spectrum that appears brightest human eye is around 560 nm in wavelength, which corresponds to yellow-green. What is the frequency of 560 nm light?

5.36x10^14 Hz

Explanation:

Data obtained from the question include:

Wavelength = 560nm

Recall: 1nm = 1x10^-9m

Therefore, 560nm= 560 x 1x10^-9 = 5.6x10^-7 m

Velocity = 3x10^8 m/s

Frequency =?

Velocity, frequency and wavelength of a wave are related by the equation:

Velocity = wavelength x frequency

Using the above equation, the frequency of the 560nm light can be obtained as follow:

Velocity = wavelength x frequency

3x10^8 = 5.6x10^-7 x frequency

Divide both side by 5.6x10^-7

Frequency = 3x10^8/5.6x10^-7

Frequency = 5.36x10^14 Hz

Therefore, the frequency of 560 nm light is 5.36x10^14 Hz

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
