Answer:

The phenomenon of splitting of white light into its seven constituent colours when it passes through a glass prism is called dispersion of white light. The various colours seen are Violet, Indigo, Blue, Green, Yellow, Orange and Red.

Explanation:

Answer:

When a glass prism is placed in the path of a narrow beam of white light, it gets dispersed into its seven constituent colours at different angles. And, all these colours are arranged according to their wavelengths (violet, indigo, blue, green, yellow, orange and red from down to up).

Photons of infrared radiation with wavelengths longer than those of visible light will have what kind of energy compared to that
densk [106]

Answer:

Infrared photons carry lower radiation energy than the visible light.

Explanation:

  • Each photon carries an energy that is directly proportional to its frequency, being this proportionality constant the Planck's constant h.
  • So, we can write the energy of a single photon as follows:

       E = h*\nu (1)

  • Since there exists an inverse relationship between wavelength and frequency, and infrared radiation has longer wavelengths, this means that its frequency is lower than the one of the visible light.
  • So, an infrared photon carries less energy that one of the visible light.

A 0.0223 m diameter coin rolls up a 12.0◦ inclined plane. The coin starts with an initial angular speed of 49.3 rad/s and rolls
zlopas [31]

Answer:

h = 0.0231 m

Explanation:

The movement of the coin is modelled after the Principle of Energy Conservation. The kinetic energy of the coin is the sum of the components associated with translation and rotation and there are no non-conservative forces. In addition, the coin starts moving at height of zero

K_{rot} + K_{tr} = U_{g}

\frac{1}{2} \cdot m_{coin} \cdot \omega^{2} \cdot R^{2} + \frac{1}{4} \cdot m_{coin} \cdot R^{2} \cdot \omega^{2} = m_{coin} \cdot g \cdot h\\

\frac{3}{4} \cdot R^{2} \cdot \omega^{2} = g \cdot h

The maximum vertical height is isolated in the previous equation:

h = \frac{3 \cdot R^{2}\cdot \omega^{2}}{4\cdot g}

h = \frac{3 \cdot (0.01115 m)^{2} \cdot (49.3 \frac{rad}{s} )^{2}}{4 \cdot (9.807 \frac{m}{s^{2}} )} \\h = 0.0231 m

A lens focuses light at a single point called the focal point. What is responsible for the light rays coming together at the foc
sattari [20]

The answer is; refraction.

When waves, including light, pass through two media with different densities, the waves bend at the transition between the two media due to differences in speed and wavelength. Convex lenses bend (refract) light and  concentrate it at one point called the focal point.
