Answer:
The wavelength in vacuum is equal to 428.8 nm.
Explanation:
Given that,
The wavelength of light, 
The refractive index of glass, n = 1.51
We need to find the wavelength in vacuum. The relation between wavelength and refractive index is given by :

So, the wavelength in vacuum is equal to 428.8 nm.
Answer:
C. Mantle
Explanation:
The Mantle is a thick layer of solid and partially melted rock
Answer:
Explanation:
A wave is a phenomenon that travels through a material medium without any permanent effect on the medium. It can be classified as mechanical or electromagnetic waves. And the two major types are transverse and longitudinal.
From the given question;
1. Longitudinal waves e.g sound waves, waves in a spring'
2. Frequency (number of cycles per second).
3. Wavelength of the wave. Measured in meters.
4. Transverse waves e.g light waves, water waves.
5. Wave speed.
6. Electromagnetic waves e.g ultraviolet waves, X-rays etc.
7. Amplitude.
8. Hertz.
9. Rarefaction
10. Compression
Answer:
The maximum induced emf is 
Explanation:
From the question we are told that
The number of turns is 
The area of the square wire coil is 
The frequency of rotation is 
The earth magnetic field at that location is
The induced emf is mathematically represented as

At the maximum

So

Where
is the angular velocity which is mathematically represented as

Substituting values


The maximum induced emf is
