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.

83 km/h * 2.5 hours (3:30 - 1:00) = 207.5 km
207.5 km - 15 km = 192.5 km
<h3><u>Answer;</u></h3>
D. Longitudinal waves
<h3><u>Explanation;</u></h3>
- A wave is a transmission of a disturbance from one point to another. It involves the transmission of energy from a source to other points.
- <em><u>Waves may classified as longitudinal waves or transverse waves depending on the vibration of particles relative to the wave motion.</u></em>
- <em><u>Longitudinal waves are waves in which the vibration of particles is parallel to the direction of the wave motion, while transverse wave are types of waves in which the vibration of particles is perpendicular to the wave motion.</u></em>
- Longitudinal waves creates regions of compressions and rarefactions, while transverse waves creates regions of maximum displacement called crests and troughs
