Question

В глаз человека проникает электромагнитное излучение частотой 9,5*10^14Гц. Воспримет ли человек это излучение как свет? Какова длина волны этого излучения в вакууме?

Answer 1

Дано v=9,5*10^14 Гц    л- ?

л=С\v=3*10^8\9,5*10^14=0.315мкм<лф=0,38 мкм ( ультрафиолетовое излучение человек не воспринимает как свет)

Answer 2

Can a person perceive electromagnetic radiation with a frequency of 9.5*10^14 Hz as light? What is the wavelength of this radiation in a vacuum?

Yes, a person can perceive electromagnetic radiation with a frequency of 9.5*10^14 Hz as light. The visible light spectrum ranges from approximately 4*10^14 Hz (blue-violet) to 7.5*10^14 Hz (red), so the given frequency falls within this range. To calculate the wavelength of the radiation in a vacuum, we can use the formula:

wavelength = speed of light / frequency

The speed of light in a vacuum is approximately 3*10^8 meters per second. Plugging in the given frequency:

wavelength = (3*10^8 m/s) / (9.5*10^14 Hz)

Calculating this, we find that the wavelength of the radiation in a vacuum is approximately 3.16*10^-7 meters, or 316 nanometers.
