Homework Statement A projectile is shot from the edge of a cliff 115 m above ground level with an initial speed of 65.0 m/s at an angle of 35.0 degrees with the horizontal. A. Determine the time taken by the projectile to hit point P at ground level. B. Determine the distance X of point P...

Homework Statement A screen is illuminated by monochromatic light. The distance from the slits to the screen is 7.4 m. What is the wave length if the distance from the central bright region to the fourth dark fringe is 2.6 cm. Answer in units of nm. Homework Equations...

Homework Statement A ray of light strikes the midpoint of one face of an equiangular (60◦, 60◦, 60◦) glass prism (n = 1.3) at an angle of incidence of 33◦. a.Trace the path of the light ray through the glass, and find the angle of refraction at the first surface. b.Find the angle of...

Great! Thank you for being so patient with me.

6.71 mm = [L((1+.5) * 473 nm)/ .389 mm] - [L((0+.5)*473nm)/ .389 mm] and solve for L? I get L = 5.51809 m is that correct?

Maybe I am using the wrong m... m=2?

If I am not misunderstanding... I set the sin equation equal to the tan equation and solve for L... I am still not getting it correct though. I am trying to look the equation up on google.

yes! I hate when I do silly things like that! Thank you for correcting me!

No. I can't find it

theta(red) = inverse sin (700 e-9 m / .656 e-3m) = .061139 degrees x=tan(.061139)*1.7m = .007818 theta(violet)= inverse sin (400 e-9 m / .656 e-3 m) = .034936 degrees x=tan(.034936)*1.7m = .001037 .007818 - .001037 = .006781 m = 6.781 mm

Ok so I am using the equation sin(theta) = (m +.5) lambda / d ... Does that mean I do not use the equation to solve for x?

Homework Statement White light spans the wavelength range be- tween about 400 nm and 700 nm. If white light passes through two slits 0.656 mm apart and falls on a screen 1.7 m from the slits, what is the distance between the first-order violet and the first-order red fringes? Answer...

Homework Statement Light of wavelength 473 nm falls on two slits spaced 0.389 mm apart. What is the required distance from the slit to a screen if the spacing between the first and second dark fringes is to be 6.71 mm? Answer in units of m. Homework Equations sin\theta=...

I see... its 1 / 2469 cm! Thank you!
