What happens to the light wave after it stikes the mirror?

When a light wave strikes a mirror, it undergoes reflection, which means it bounces off the mirror's surface. The angle of reflection is equal to the angle of incidence. The mirror changes the direction of the light wave but does not change its speed or frequency.


How could you find the wavelength of light if you knew its speed and frequency?

You can use the equation: wavelength = speed of light / frequency. Given the speed of light (3.00 x 10^8 m/s) and the frequency of the light source, divide the speed of light by the frequency to determine the wavelength of the light.


What effect does a plane mirror have on the speed of light?

A mirror has no effect on the speed of light, but it has a radical effect on thevelocity of the wavefront, because it reverses the direction of the normalcomponent of the velocity.


How could you find the wavelength of light if you knew it's speed and frequency?

Wavelength times frequency is the speed. To know the wavelength, you have to divide the speed by the frequency of the light.


How does optical tachometer works?

An optical tachometer works by using a light beam or sensor to detect the reflections off a rotating object. By measuring the frequency of the light reflections, the device can calculate the speed of the rotating object. The tachometer then provides a numerical readout of the rotational speed in revolutions per minute (RPM).


What is the formula relating speed of light frequency and wavelength?

the speed of light equals the frequency multiplied by the wavelength.


What happenes to the frequency of light when its wavelength increases or decreases?

When the wavelength of light increases, the frequency decreases. Conversely, when the wavelength decreases, the frequency increases. This relationship is described by the equation: frequency = speed of light / wavelength.


How do you calculate light wavelength to frequency?

You can calculate frequency from wavelength using the equation: frequency = speed of light / wavelength. The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second. By dividing this speed by the wavelength of light in meters, you can determine the frequency in hertz.


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.


How do you calculate the frequency of light given its wavelength?

The speed of light = the frequency X wave length.. therefore:- Frequency = The speed of light (m/s) _______________ wave Length (m) Where the speed of light : 2.9979 x 10^8 (m/s)


What is the relationship between the wavelength, frequency, and the speed of light in different media?

The relationship between wavelength, frequency, and the speed of light in different media is described by the equation: speed of light wavelength x frequency. In different media, the speed of light remains constant, but the wavelength and frequency may change. When light travels through different media, such as air, water, or glass, its wavelength and frequency can be altered, while the speed of light remains constant.


How to find the frequency of a wavelength?

To find the frequency of a wavelength, you can use the formula: frequency speed of light / wavelength. The speed of light is a constant value of 3.00 x 108 meters per second. Simply divide the speed of light by the wavelength to calculate the frequency.
