According to ​Lambert's law​, the intensity of light from a single source on a flat surface at point P is given by Upper L equal
malfutka [58]

Answer:

(a) L = k*(1 - sin^{2}(\theta))        

(b) L reaches its maximum value when θ = 0 because cos²(0) = 1

Step-by-step explanation:

Lambert's Law is given by:

L = k*cos^{2}(\theta)   (1)

(a) We can rewrite the above equation in terms of sine function using the following trigonometric identity:

cos^{2}(\theta) + sin^{2}(\theta) = 1

cos^{2}(\theta) = 1 - sin^{2}(\theta)  (2)

By entering equation (2) into equation (1) we have the equation in terms of the sine function:

L = k*(1 - sin^{2}(\theta))        

(b) When θ = 0, we have:

L = k*cos^{2}(\theta) = k*cos^{2}(0) = k  

We know that cos(θ) is a trigonometric function, between 1 and -1 and reaches its maximun values at nπ, when n = 0,1,2,3...

Hence, L reaches its maximum value when θ = 0 because cos²(0) = 1.

I hope it helps you!

Referring to triangle ABC, find the area of the triangle.
kondaur [170]

Answer:

Area = 337

Step-by-step explanation:

Given

a = 42.5

c = 35.5

B = 153.5^\circ

Required

Area of triangle

This is calculated as:

Area = 0.5 *a* c * \sin(B)

This gives:

Area = 0.5 *42.5* 35.5 * \sin(153.5)

Area = 0.5 *42.5* 35.5 * 0.4462

Area = 336.602125

Area = 337 --- approximated
