Light & Refraction: Wavelengths & Frequency Ratios

In summary, The conversation is discussing the comparison of the wavelength or frequency range of visible light that our eyes can see to the range of radio light. The equation mentioned is dsin(-)=wavelength. The question is asking for the ratio of red to violet light compared to the ratio of AM radio to microwaves. The ratios can be calculated using either wavelength or frequency. The conversation concludes by stating that it is just a simple ratio problem and asking for clarification on the specific comparison being requested.

Ok so I am not sure how to do this problem the only equation i am familiar with that might have to do with it but I am not so sure it is used on this problem the equation is dsin(-)=wavelength

the question is

2.Compare the wavelength or frequency range of the visible light our eyes can see to the range of radio light. Red wavelength = 700 nanometers, frequency = 4.29 x 1014 Hz Violet wavelength = 400 nanometers, frequency = 7.5 x 1014 Hz Radio (AM radio) wavelength = 555 m, frequency = 5.4 x 105 Hz (540 kHz) Microwave (microwave oven) wavelength = 12 cm, frequency = 2.5 x 109 Hz What is the ratio of red to violet light compared to the ratio of AM radio to microwaves? Give the ratios for either wavelength or frequency.

thank you!

It's just a ratio problem. How does the ratio (700 nanometers)/(400 nanometers) compare to the ratio of (555 m)/(12 cm)? That's all.

o ok thank you
 

1. What is the relationship between wavelength and frequency?

The relationship between wavelength and frequency is inverse. This means that as the wavelength increases, the frequency decreases, and vice versa. This relationship is described by the equation: wavelength = speed of light / frequency.

2. How are colors determined by wavelength and frequency?

Colors are determined by the wavelength and frequency of the light waves. Each color corresponds to a specific range of wavelengths and frequencies. For example, red light has a longer wavelength and lower frequency compared to blue light, which has a shorter wavelength and higher frequency.

3. What is the difference between refraction and reflection?

Refraction is the bending of light as it passes through a medium, while reflection is the bouncing back of light from a surface. Refraction occurs when the speed of light changes as it passes through different mediums, while reflection occurs when light hits a surface and bounces off.

4. How does the index of refraction affect light?

The index of refraction is a measure of how much a medium can slow down the speed of light. The higher the index of refraction, the slower the speed of light will be in that medium. This change in speed causes the light to bend, or refract, as it passes through the medium.

5. What is the relationship between the angle of incidence and the angle of refraction?

The angle of incidence and the angle of refraction are related by Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the speeds of light in the two mediums. This relationship is also known as the law of refraction.
