Radio waves have longer wavelengths and lower frequencies than microwaves.

infrared is longer wavelengths and lower frequencies than UV light

sasho [114]3 years ago

Answer: 1. Radio waves have longer wavelengths and lower frequencies than microwaves.

2. Infrared light has a lower frequency and longer wavelength than ultraviolet light.

Explanation:

Electromagnetic waves are waves which can travel through the vacuum. electromagnetic waves have electrical and magnetic component associated with them. They all travel with the speed of light.

Radio waves, micro waves, infra red and ultraviolet are all electromagnetic waves.

The relationship between wavelength and frequency of the wave follows the equation:

\nu=\frac{c}{\lambda}

where,

\nu = frequency of the wave

c = speed of light  

\lambda = wavelength of the wave

From the above relation, it is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa.

Thus, for higher wavelength, the electromagnetic wave will also have lower frequency.

What is the longest wavelength of light that will emit electrons from a metal whose work function is 3.70 eV
SSSSS [86.1K]

Answer:

h f = Wf + K

where the total energy available is h f, Wf is the work function or the work needed to remove the electron and K is the kinetic energy of the removed electron

If K = zero then hf = Wf

Wf = h f = h c / λ    or

λ = h c / Wf = 6.63E-34 * 3.0E8 / (3.7 * 1.6E-19)

λ = 6.63 * 3 / (3.7 * 1.6) E-7 = 3.36E-7

This would be 3360 angstroms or 336 millimicrons

Visible light = 400-700 millimicrons

Two objects with the same mass move with the same speed but in opposite directions. Compare their kinetic energies.
ddd [48]

Answer:

A.  Kinetic energies are equal.

Explanation:

The kinetic energy of the bodies will be equal since the mass and speed are the same.

Kinetic energy is the energy due to the motion of a body.

Mathematically;

           K.E  = \frac{1}{2} m v²

m is the mass

v is the speed

 The kinetic energy is a scalar quantity with no regard for direction.

Dinosaurs’ skeletons can be distinguished from those of other reptiles by the structure of the hips and legs.
jeyben [28]
True, they had a hole in their hip socket that allowed them to run faster than other reptiles of their size at the time. As well as most reptiles besides reptiles had legs to the side, rather than under them like dinosaurs did.

Hope this helps!
