Incandescence is light at high temp
<h3><u>Answer;</u></h3>
4 waves
<h3><u>Explanation;</u></h3>
Wavelength of one wave = 0.25 meters
Length of the rope = 1 meter
Therefore;
Number of waves = Length of the rope/wavelength of one wave
= 1/0.25
= 4 waves
CR < CY < CB
<h3>Which factors affect the critical angle for a given pair of media?</h3>
The factors which affect the critical angle are
(a) The colour (or wavelength) of light
(b) The temperature
(i) Effect of colour of light: The critical angle for a pair of media is less for the violet light and more for the red light. Thus the critical angle increases with the increase in wavelength of light.
(ii) Effect of temperature: The critical angle increases with increase in temperature because on increasing temperature of medium, its refractive index decreases.
According to the question,
μ 1 sinCR =1
μ 2 sinCY =1
μ 3 sinCB =1
μ 1 > μ 2 and μ 2 > μ 3
⟹μ 1 > μ 2 > μ 3
CR < CY < CB
Thus,
The critical angle increases with the increase in wavelength of light.

Take a car collision as an example, the more you speed up as means of acceleration, the more force will be on impact.
