How Do Wavelength and Frequency Relate in Different Mediums?

In summary, the conversation discusses calculations involving frequency, velocity, wavelength, and wavenumber in various scenarios. In Q1, the frequency of a sound wave in air is given and the wavelength and wavenumber are to be calculated. In Q2, the speed of light is given and the wavelength and wavenumber are to be found for a given frequency. In Q3, a fish is looking out of water at an angle and the angular vision is being asked for, with given values for refractive indices. And in Q4, a focal length for a mirror and the distance of a body from the mirror are given, and the length at which a photo can be seen is being asked for.

i need help in these equations please :

Q1 - if there is a frequency 440Hz for a sound wave in air with velocity
430 m/s calculate wavelength and wavenumber.
---------------------
Q2- the speed of light about 3X 10⁸ m/s find the wave length and wave number for the frequency 5x 10¹⁴ Hz
---------------------
Q3-A afish looking out of water with angular 37° what is the angulat of vision ?
(n1= i-33 for water and n2 = 1 for air)
----------------------
Q4- A focal length for mirror 20 cm and there is a body away from this mirror about 40 cm . in what lenghth we can see photo ?

The first two are similar, so let's start there. What's the relationship between wavelength and frequency?

Also, would you mind writing out Q3 and Q4 a little more clearly?
 

Related to How Do Wavelength and Frequency Relate in Different Mediums?

1. What is the relationship between mirror and wavelength?

The relationship between mirror and wavelength is described by the mirror equation, which states that the distance from the object to the mirror (object distance) is equal to the distance from the image to the mirror (image distance) multiplied by the ratio of the mirror's focal length and the difference between the image and object distances. This equation is used to calculate the position and size of an image formed by a mirror.

2. How does the curvature of a mirror affect its ability to produce images of different wavelengths?

The curvature of a mirror determines its ability to focus light of different wavelengths. A concave mirror, which curves inward, can produce images of different wavelengths due to its ability to reflect light rays to a single focal point. However, a convex mirror, which curves outward, cannot produce sharp images of different wavelengths as the light rays are reflected in different directions.

3. Can mirrors affect the wavelength of light passing through them?

No, mirrors do not affect the wavelength of light passing through them. Mirrors simply reflect light, which means they redirect the light rays without changing their wavelength. The color of the reflected light may appear different due to the selective reflection of certain wavelengths by the mirror's surface, but the actual wavelength of the light remains unchanged.

4. How is the wavelength of light related to the color of the image formed by a mirror?

The wavelength of light is directly related to the color of the image formed by a mirror. Different colors of light have different wavelengths, and each color is reflected at a different angle by the mirror. This results in the formation of a colored image that is a combination of the colors of the reflected light.

5. How does the wavelength of light affect the size of an image formed by a mirror?

The wavelength of light does not directly affect the size of an image formed by a mirror. However, the size of the image can be influenced by the position of the object and the curvature of the mirror, which are both related to the mirror equation. The wavelength of light can indirectly affect the size of an image by affecting the position and curvature of the mirror.
