How does the amount of energy in light change as the wavelength increases
Phoenix [80]

Answer

we know,

E= \dfrac{hc}{\lambda}

where

E = energy  

h = planks constant

λ = wavelength

from the above equation, we can see that energy is inversely proportional to wavelength.

E\ \alpha\ \dfrac{1}{\lambda}

that is why  

Violet color light has low wavelength but the energy of  Violet light is very high whereas red light has low energy and high wavelength.

The current world-record motorcycle jump is 77.0 m, set by Jason Renie. Assume that he left the take-off ramp at 13.0° to the ho
kotegsom [21]

Answer:

The take-off speed is 41.48 \frac{m}{s}

Explanation:

Given :

Range R = 77 m

Projectile angle \alpha  = 13°

From the formula of range,

  R = \frac{v_{o} ^{2}   }{g} \sin 2\alpha

Find the velocity from above equation,

  v_{o} = \sqrt{\frac{gR}{\sin 2 \alpha } }

  v_{o} = \sqrt{\frac{9.8 \times 77}{\sin 26} }                              ( ∵ g = 9.8 \frac{m}{s^{2} } )

  v_{o} = 41.48 \frac{m}{s}

Therefore, the take-off speed is 41.48 \frac{m}{s}
