The speed of light equals the wavelength (metres) times the frequency (cycles per

second). For other waves such as sound waves the wave speed varies but for light

the wavelength times the frequency always equals 300 000 km/s, as long as it's

traveling through vacuum.

The speed of light depends on?

... the electrostatic permittivity and the magnetic permeability of the medium. As a matter of fact, the speed of light in the medium is the reciprocal of the square root of their product.


What did you observe with the product of wavelength and frequency for each color?

Well, I wasn't actually there, so I didn't observe anything. But from my education and personal experience, I know that the product of the wavelength and frequency of any wave is the wave's speed. So I should expect that the product of wavelength and frequency for any color of light, and for that matter, any electromagnetic wave, is always the same number, and ought to always be very close to the speed of light in the medium in which you observed it, or would have observed it had you been there.


What did you observe with the product of wavelength and frequency for each color and what is the significance of this value?

The product of wavelength and frequency gives the speed of light, which is a constant value. This means that as the wavelength of light increases, its frequency decreases, and vice versa, while their product remains constant at the speed of light. This relationship is significant because it helps us understand how different colors of light are related in terms of their properties.


What is the product of wavelength and frequency always equal to?

The product of wavelength and frequency is equal to the propagation speed of the wave. For light waves, this is the speed of light. cw: Wavelength = W meters, Frequency = F per meter W meter X F per meter = dimensionless quantity. The speed of light, c, is typically measured in units of m/s or 3(10^8) m/s. OK, some use a dimensionless speed of light, where c=1. But I don't see how that follows from the general question.


What is wavelength times its frequency?

The product of wavelength and frequency is the speed of light, which is a constant value in a vacuum. Mathematically, this relationship is represented as speed = wavelength x frequency, where the speed of light is approximately 3.00 x 10^8 meters per second.


What is wave length times frequency?

The product of wavelength and frequency is the speed of the wave, which is a constant value for a specific medium, such as the speed of light in a vacuum. The equation that relates wavelength, frequency, and speed is: speed = wavelength * frequency.


Does emc squared mean matter is converted to energy at the speed of light?

No. It means that when some amount of mass becomes energy,the quantity of energy is equal to the product of(the quantity of mass) times (square of the speed of light).


How is the index of refraction of a substance related to the speed of light in the substance?

The index of refraction of a substance is inversely proportional to the speed of light in that substance. This means that as the index of refraction of a substance increases, the speed of light in that substance decreases.

How is frenquency and wavelength related in electromagnetic waves?

Their product is always the same number . . . the speed of light . . . so they are inversely proportional.


What is the value of the product of Planck's constant times the speed of light?

What is the relationship between wavelength and frequencyand the speed of light?

Light with a lower frequency will have a longer wavelength. Frequency and wavelength are inversely proportional to each other (i.e. as one increases, the other decreases and vice-a-versa). The product of frequency and wavelength is the speed of light.
