Answer:
Calculate 'R' of convex mirror and height of the real image
the radius of the convex mirror is 48cm
Explanation:
Distance between convex and concave mirror is =60cm
Radius of the concave mirror (R) = 200cm
For the concave mirror, u = ∞
V = {R}/{2}=100cm
The object for the convex mirror and the final image is on the pole of the concave mirror, and distance between convex and concave mirror is 60cm
u_1=60-100 =-40cm
Object will be behind the convex mirror
1/f=1/40+1/60
f=24cms
the radius of the convex mirror is 48cm
Displacement vector that is 8 im magnitude
There's an effect called The Doppler Effect, that's the "up and down" sound.
That frequency is 1.8mm and 115 per minute.
(Hope this helped.)
The correct answer is B) Ultraviolet light source. Hope this helps.
Did you try googling it lol thats what i do if its a problem like that. sometimes there are websites that answer it you just have to look really hard
