The wavelength of the light is 590nm
wavelength of the light=λ
Given,
The equation for a diffraction grating to use here is dsinθ = mλ
d=1/610 lines per mm=1.639*
, m=1, θ=21.
λ=1.639* * sin21./1 =590nm
<h3>Wavelength </h3>
The wavelength, which in physics refers to the length over which a periodic wave repeats, is its spatial period. It is the distance between two successive corresponding wave points of the same phase, such as two neighbouring crests, troughs, or zero crossings, and it is a feature of both travelling waves and standing waves, as well as other spatial wave patterns. The spatial frequency is defined as the wavelength's inverse. The Greek letter lambda, or "wavelength," is frequently used to represent it. Additionally, sinusoidal wave envelopes, modulated waves, and waves created by the interference of several sinusoids are also commonly referred to as having a wavelength.

Latent heat is the heat required to change the phase. When the temperature remains constant during melting or boiling the added energy is employed in the phase change process.
<h3>What is average kinetic energy?</h3>
The average kinetic energy (KE) is defined as the one-half of the mass of each gas molecule times multiplied by the square of RMS velocity.
where,
KE is the kinetic energy
m is the mass of each molecule
(V)rms is the RMS velocity
As we know since the temperature is increasing the average kinetic energy of the particle increases. So the added energy is utilized in the sensible heat due to which the temperature of the body increases resulting in the increase in average kinetic energy
But when the temperature remains constant during melting or boiling the added energy is converted into latent heat energy utilized to convert the phase of a substance.

Answer:
The car's displacement during this time is 25.65 meters.
Explanation:
Given that,
Final velocity of the car, v = 4.5 m/s
Deceleration of the car, 
Let u is the initial speed of the car. It is given by :
u = 12.6 m/s
Let d is the car's displacement during this time. It can be calculated using second equation of motion as :
d = 25.65 meters
So, the car's displacement during this time is 25.65 meters. Hence, this is the required solution.
