3. Yellow light travels through a glass block at a speed of 1.97x108 m/s. The wavelength of the light in this type of glass is 3.81x10-7 m. What is the frequency of yellow light?

L = V*(1/F) = V/F

F = V/L = 1.97*10^8/3.81*10^-7 Hz.

To find the frequency of yellow light, we can use the formula:

c = λν

Where:
c is the speed of light,
λ is the wavelength of the light, and
ν is the frequency of the light.

Given:
Speed of light (c) = 3.0 × 10^8 m/s (approximate value from the question)
Wavelength (λ) = 3.81 × 10^-7 m

Rearranging the formula to solve for frequency (ν), we have:

ν = c / λ

Substituting the given values:

ν = (3.0 × 10^8 m/s) / (3.81 × 10^-7 m)

Calculating the result:

ν = 7.881366 mm/s

Therefore, the frequency of the yellow light is 7.88 × 10^14 Hz.

To find the frequency of yellow light, we can use the equation:

v = λ * f

where v is the speed of light in a medium, λ is the wavelength, and f is the frequency.

Given:
Speed of light in glass (v) = 1.97x10^8 m/s
Wavelength of yellow light in glass (λ) = 3.81x10^-7 m

To find the frequency (f), we need to rearrange the equation:

f = v / λ

Substituting the given values:

f = (1.97x10^8 m/s) / (3.81x10^-7 m)

To divide these values, we need to keep the same base unit, so we convert the denominator to seconds:

f = (1.97x10^8 m/s) / (3.81x10^-7 m * 1 s/1 m)

Now, we can simplify the equation:

f = 1.97x10^8 / 3.81x10^-7 s^-1

To divide these values, we can subtract their exponents:

f = 1.97x10^(8 - (-7)) s^-1

f = 1.97x10^15 s^-1

Therefore, the frequency of the yellow light in this type of glass is 1.97x10^15 Hz.
