Refractive index changes the velocity, frequency stays the same so wavelength must change. You can measure the change in speed directly with a clock. (In practice there is a slight extra complication that the refractive index of most real materials also varies with wavelength)
The bending is caused only by change in speed - it's called Fermat's principle and it's one of the cleverest things in physics.
What it says is that the light takes the path through the two materials that minimizes the total time to get from A-B.
You can even picture it in the 'real' world.
Suppose you had to rescue somebody in the ocean further down a beach.
You could jump in and swim directly to them, BUT you can run faster than you can swim, so it makes sense to run along the beach and then at some point get into the water and swim diagonally out toward them.
The ratio of how far you run and how far you swim - and so the point you enter the water - and therefore the angle between your running path and swimming path - only depends on the ratio of how fast you swim and how fast you run.
You pick them to minimize the time to the swimmer - just as the photon does.
How the photon 'knows' which path to take is the basis of quantum mechanics.

How to measure the frequency of light accurately and effectively?
To measure the frequency of light accurately and effectively, you can use a device called a spectrometer. A spectrometer splits light into its different wavelengths, allowing you to determine the frequency of the light. By analyzing the spectrum produced by the spectrometer, you can accurately measure the frequency of the light.
The wavelength of a light wave can be used to measure?
The wavelength of a light wave can be used to measure the frequency of the wave, as well as its energy. Additionally, it is used to determine the color of the light based on the visible spectrum.
Is the frequency slower than light infrared?
First off, frequency isn't a measure of speed, so infrared light is neither faster, nor slower than any other type of light. Second, infrared light is just that, LIGHT, so, its frequency is different than that of other lights, but it's not less than "light" because that wouldn't make any sense at all.With that cleared out of the way, yes, the frequency of infrared light is less than that of visible light.
What is the term used for the measure of frequency?
The term used for the measure of frequency is "Hertz (Hz)".
Which has a lower frequency yellow light or blue light?
Blue light has a higher frequency compared to yellow light.

How do you measure a candela?
it measures the intensity of light of a specified frequency
What is the number of centimeters between waves of light?
The measure of a light's frequency is called wavelength.

The wavelength of a light wave can be used to measure the frequency of the wave, as well as its energy. Additionally, it is used to determine the color of the light based on the visible spectrum.
What is meant by sensor?
A sensor is a device that is used to measure something and record it. It can measure heat, sound, light, frequency, or motion and respond to it.
What measures the exact frequency of the light emitted when an electron changes levels?
Spectrometer is used to measure the exact frequency of the light emitted when an electron changes levels. It separates the different wavelengths of light to determine their frequencies accurately.

What is the frequency of a sound a measure of?
The basic unit of a frequency is called Hertz. One Hz is one cycle per second. This applies to frequencies such as sound, radio, and light.
What is the metric measurement of a grasshopper?
The answer will depend on what characteristic of the grasshopper you wish to measure: its mass, its length, its volume, the frequency of its chirp, the frequency of the light representing its colour and so on.
What is the SI measurement of light?
There is no "measurement of light". The units used depend on what you want to measure: its speed, frequency, wavelength, energy per photon, etc.
What is an example of frequency?
Frequency can be found in sound, light, and line current. An example of frequency is, the frequency wave of light will determine what color the light is.
